A famous line yelled by Al Pacino in the movie Scarface.

A pick me is a woman that is willing to do anything for male approval. She will embarrass or throw other women under the bus to achieve this goal. The unfortunate thing about a pick me is usually the men they are trying to seek approval from are of poor quality and treat women badly, leaving little real benefit for the pick me.

What Tony Montana, aka Scarface, screams as he blasts the door with his "little friend."

a phrase commonly used by a person before they attack someone with a weapon, usually a machine gun or grenade launcher

As well as being said in Scarface, this line is also said (copied) in the hilarious film Mafia!

its a quote from the movie scarface which has become poular amoung people to say when they do things like expose thier penis or pull out a gun, or a baseball bat, a chainsaw, flip someone off, etc.
it is a way to imitate the persona of tony montana.
