rasta imposta:
A person, usually a hipster, who claims to live a Rastafarian lifestyle, but in reality doesn't at all, whatsoever. Tons of stoners claim to be Rastafarian, but the only thing they do is smoke weed and wear Rasta bracelets.
dean: i'm rastafarian
me: what do rastafarians believe in?
dean: ummmmmm. look at my bracelets!
me: you're a rasta imposta
i'm no rasta, and i have no indepth knowledge of the religion, what is stands for, etc.. but it just kinda bugs me when people wear all this rasta shit and have no clue about the religioug significance. but whatever, i guess, youre style isnt my business...
end rant.
