The Fonzi

After you bust a nut in a girls mouth you cock slap her in the face, put two thumbs out and say "heeey" like the Fonz in happy days.

Nancy was blowing Thad in the back of his 1975 thunderbird and he proceeded to give her the Fonzi.

The Fonzie

While enjoying a cigarette after a night of intense sex, look your partner in the eyes, point at them with both fingers, and moan out "AYYYYYYYYYEE" in your best Fonzie impression, cigarette between your teeth

Friend 1 : "Yea so we fucked all night and then she pulled The Fonzie on me"
Friend 2 : Marry her, my dude"
