A dro is the one thing you do not want as a friend. it is the ultimate example of a fake, unreliable, annoying, and everything in between type pf person. he is the guy that acts cool with you but really isn't. she is the girl that seems interested and never calls you back. it is the worst of the worst of any type of person and if you do not know a dro, then consider yourself lucky.
James:man, fuck Cody!! he owes me $200 and doesn't answer my calls!!!
Bryant:man, Cody is a fucking dro.
