A word that Joe
Pesci uses in a lot of his films, especially Goodfellas and
Casino.
It's also a word that others mimic to sound like Joe
Pesci and to try to be humorous.
"Hey
Brandon, do your
best Joe Pesci impression!"
"You Muddafucka, you!"
Or (Joe Pesci in Goodfellas) "Go
home and get your fuckin' shinebox!"
"You Muddafucka, you Muddafuckin' mutt!!"
