Big Mouth Wiki

This is Guy Town. I originally came here to do a story about a lumpy gourd of a boy, but I ended up learning a few things about what it means to be a man. Sometimes being a man means putting the ones you love first, and sometimes it means owning up to your mistakes. Not all men value the same things, and that means you can be any man you want. All you need to do is figure out who you are and be true to yourself.
—Matthew MacDell in Guy Town

Matthew MacDell is one of the main characters in Big Mouth. He is the only openly gay character in season 1 whose shtick seems to be appearing from off-screen (or being cut to) and injecting an appropriate quip related to the current conversation, and later on in seasons 3 and 4, he would become a more detailed, and developed character. He is voiced by Andrew Rannells. He is dating Jay Bilzerian



Matthew was born in 2004 to Edward MacDell and Kimberly MacDell who grew up in Austin, Texas and he was the first born in a family of two other brothers and two sisters. Matthew's parents were a very conservative and traditionalist couple, who taught their views to their kids. and of course, these values were only amplified by the fact that they lived in Texas.

Ever since he was a kindergartener, Matthew always knew he was into boys. As seen in "Obsessed", Matthew had a celebrity crush on Harry Potter and pretended he was his boyfriend, along with Nick Jonas when he was a bit older.

Sometime during his childhood, Matthew took up tap dancing.

Other kids at Matthew's school knew he was gay and they would constantly bully him for it, calling him "The Steer Queer".

Sometime during elementary school, The MacDell Family would move from Texas to New York and live in a suburban home in Westchester.

Growing up, Matthew always had a very close relationship with his mother. They would compete in the church bake-off, and do other various activities together.

Teenage Years

As a teenager, Matthew attended Bridgeton Middle School who is a lot more openly flamboyant than before. In New York's political climate, none of the other students bully him for his sexual orientation so he's a lot more proud of himself. He does the school's televised morning announcements, which he calls Morning Announcements With Matthew; a work that he treats like an actual news segment. He had become friends with Caleb, who worked as the cameraman for his show.

In "Ejaculation", Matthew befriended Jessi Glaser after seeing how funny she was.

In "Am I Gay?", he hosts the school's gossip broadcast and goads Nick Birch into claiming he had ended his and Jessi's relationship.

In "Guy Town", he trails behind Andrew Glouberman in an attempt to question him about what happened with Lola Skumpy back in her condo. Matthew is also seen to be provoked by a resident of Guy Town and gets into a gay-off with him. The resident suggests being nicer to others, and Matthew decides to give it a shot.

In "Dark Side of the Boob", he tries to be kinder towards others but finds it quite difficult, he also is shown as an outcast from others because of his sexuality. He invited Jay to crash in the teacher’s lounge with him before quickly getting in an argument with him due to the Shame Wizard’s taunting.

In "Smooch or Share", he is constantly persecuted and shamed for being the only gay student in the grade by both his classmates and the Shame Wizard. Matthew and Jay meet again in the bathroom where they continued to bicker before Jay left. A group of people including Jay later came into the teachers lounge where Matthew was staying to play “Smooch or Share”, a game that Nick made up that’s a combination of Spin the Bottle and Truth or Dare. Matthew eventually joined and Jay kissed him after the bottle landed pointing in his direction. They later made out in front of the bleachers. In the next episode when Jay approached Matthew about what happened, Matthew deemed their kiss a one-time thing and left it there.

In "My Furry Valentine", Matthew meets Aiden, another openly gay boy from another school and the two quickly become boyfriends. Proud of Matthew for making such a quick first boyfriend, Maury admits that Matthew is his favorite kid.


Matthew is considered to be "the hottest guy in the grade" (by Ali in "Rankings") with ginger hair that flicks out and cornflower blue eyes where his eyelids are normally half-closed. He tends to wear a navy blue button-up under a light brown sweater-vest, accompanied by white jeans with a brown belt. He's mostly caught frowning and only smiles when necessary, though he seems to smile more after Season 5.


Matthew is generally a upbeat boy, but he can turn hostile in a breath where he is given to clever witticisms and insightful zingers and enjoys delivering them, especially when they are deserved. In spite of his snarky nature, he is supportive of his classmates, offering sound advice when called upon. He shows to be quite sensitive when it comes to being cast aside from the other students because of his sexuality. He is prone to overt hand gestures and deliberate posturing. He is the typical gay stereotype. He enjoys baking with his mom which he has done since he was young.
