A fat woman's vagina. Fat women tend to have slightly hotter vaginas than skinny women, hence; a twat like an oven.
I know she's ugly, but I'll still fuck her. You know she's got an oven twat.

Get the oven twat mug.
When you put your dick in the vagina and twist the clit like a dial to heat your meat
Quentin: I used that pussy like a Twat Oven.
Norman: You useless sack of shit.
