NATO

No Action Transport Only. Refers to a guy attached to a group of females, usually no more than four.

The male is in love with one or more of the women, but, alas, ihs love is not reciprocated. The guy is used solely because he has a car, and the girls do not, so they lead him on and use him for transportation purposes only.

A: Look at Bob, hanging out with all those chicks.
B: Nah, man, nothing's going on, he's just NATO.
