A fat woman's vagina. Fat women have slightly hotter vaginas than skinny women, hence; hot twat.
Man, your girlfriend is chubby! Yeah, but she's got a hot twat.
A very well trimmed and very sexy pussy that turns you on so much you can't help but be a "Hungryman" on an "Extended Stay" putting you at risk for "tacochin", "Bungtongue" and possibly "FUBA"
She has such a hot twat that I dropped everything I was doing to go on an extended stay with her.
This is the conclusion to what happens when you fool around with your girl after handling or eating spicy peppers (ie: jalepeno, serrano, habanero, etc.)
Bro, my girl was sooooo mad at me for giving her that Hot Twat. I shouldn't have ate those hot wings dog.
