RobT is something you call a person, when they act weird around girls. If you catch a guy acting weird around a girl, maybe he is nervous or being weird then shout "ROBT".
This is a commen thing to say when you are out in town for the night and see they boys trying to get some gals.
You walk by a boy and a girl. The boy is acting goofy around the girl, and then you shout "ROB-T"
