When a chick has a body like toothpaste, i.e. curvy in all the right places. Note how it can only apply to her figure; you must ignore the face at all costs.
"Bro, that new teacher's pretty fine, she's got a toothpaste body"
"...Yo, what the fuck are you talkin' about?"
"Nevermind the face, but you know when you squeeze her body it's like Colgate man"
"Dude stfu she's your mom lol"
