1 definition by Bob Marley's Girl

A young/old individual who is trying to act gangster (and/or says that they are gangster) but instead ends up acting/sounding extremely gay, and preposterous.
Foolio:
"Oh! I'm so gangzzta! Yo, I'm like dee bomb digity, if ya'll know wut I meeeen! Hehehe! Cuz I'm gangster layyk dat!"

Smart-ass:
"No, you're not a gangster, you're a gayster."
