A Larry Bird 

A large Caucasian penis. Named as such because Larry Bird is known as one of,if not the only, Caucasian basketball player who can HANG with the perdomintly African American legends of basketball by their own admittance. Much like the majority of well endowed penises are of African American descent. Could also be referred to as the "Dick from French Lick".

Usually she prefers an all BBC team, but if a Larry Bird is around, she'll run with that unit.

A Larry Bird 

When you are having sex with a girl during a lightning storm and then there is a flash of lighning and during the split second that you cant see the girls brother pops out of the closet and switches places with her so when you regain your sight you realize you are actually fucking the girls brother.

Also known as "The Ol' Switch-a-roo"

Tom: Dude you will not believe what happened to me the other day.
Jack: What?
Tom: Well I was with this girl at my place and we got into it and then there was a flash of lightning and she pulled A Larry Bird!
Jack: My god...
