Weirdgirl C!Tommy, is a concept that was born on twitter. It is a headcanon in the dsmp fandom, that Tom Simons,
dsmp character, Tommy, is a trans girl. More specifically a Weirdgirl. Weirdgirls are girls who are, well, weird. They often are associated with undiagnosed
Autism and/or
ADHD, and often have weird mannerisms and/or interests.
The headcanon is spread by different twitter users, but mostly by @GRAVEYARDFUNK on twitter, who also recently revived the headcanon which spread controversy around headcanoning characters as
trans feminine.
