A woman seen to be so "saucy" or attractive that she would in fact cause you to fill your pants with your sauce. Usually yelled at women from across the street or from a moving vehicle.
Tom: hey dude, check out saucy pants over there
Mark: oh man, i think i just came in my pants
"So this tranny is just saucking me on the Q Line, drooling, trying to fix his broken clear pump heel at the same time, and this goddamn transit cop walks in."
A saucy hammer is when the man puts his penis in the girls mouth and she gets under him. Once she's under him the man proceeds to do pushups while having his penis in her mouth.
