v. to whisper the phrase "murphballer" into a girl's ear while you are having sex with her. A popular variation is to yell "MURPHBALLER!" as you reach orgasm. Also, considered an anthem in the streets of many Chicagoland neighborhoods, namely Hyde Park and La Grange Park.

Named after Dave who was featured in such films as "Major Dunkage" and "Major Dunkage 2"
