Def 1. A gangster who has lost his getto style and is still trying.
Def 2. Something that is trying to be getto but really is not.
A gangster is talking white and a girl walks and says, "You are so gansterlika." Or... Nike came out with a shoe called Compton and it really just looks like a golf shoe, the gangster will say to the cashier, "Your shoe Compton is Gangsterlika."
