I talked to a friend in New York today. He mentioned that when a guy is thirsty for sex, they would say the guy is "gunbag" ( which I am not sure if it is the right spelling, but its pronunciation sounds like this).
I wonder which word he was using. I do not think that it spells gunbag because I did not find many results when I serach gunbag on Google. Does anyone have a clue about this?
