The act of fucking someone ferociously
Boy: Hey girl wanna fuck?
Girl: Why don't we Plof?
Boy: You are a sex goddess
It can be defined.
1.) A plof is the act of farting when someone is sucking your dick.
Ex. - Normally I wouldn't let Angelina Jolie suck my dick. But I would if she were being fucked by Brad Pitt; but, I'd still plof her.
Plof can not be defined.
Jim said, "Yeah man, I totally plofed that chick." To which
Tom responded, "Plof."
(Jim incorrectly uses the word, which causes Tom to correct
his usage of the word by using the word himself.)
