snaggle tooth twat monster
A fugly waitress with poor dental hygiene that smells of whore's crotch who serves sandwiches while wearing a mini (and I do mean mini) skirt with what looks like roast beef dangling between her legs.
Wow, I've seem to have lost my appetite for Arby's since seeing that snaggle tooth twat monster.
Tooth Tarnishing Twat
Someone who's breath smells so bad, not only does it disconcertingly resemble the oddly specific stench of a sweaty vagina, it also gives other people cavities.
*scrunches face in disgust* "Jesus Christ Bill, brush your teeth, you tooth tarnishing twat"
