The guy who people use to give them rides. Someone who is a taxi is usually a male who is being used by a girl (but occasionally a guy), and has no balls to say "Am I ever going to get ass, cash, or grass for this?", which leaves him to linger with the thought that one day he just might, allowing girls everywhere to take advantage.
Jamie: "hey ashley, lets call up our taxi to take us to that party full of cute guys"
Ashley:"Yeah, just make sure we sweet talk him, so he thinks that he's gonna get something out of it haha"
