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!!"
