The term Sperm Aqueduct can also be used with homosexual connotations also. SEE EXAMPLE 2

2: Billy’s is such a homo that his ass is becoming a sperm aqueduct, like his mother’s.
When the loose skin of the scrotum is pinched with both hands (preferably with one hand on each nut) and stretched upward covering the majority of the testicles and shaft of the penis. This leaves the head of the penis popping out like a "baby kangaroo".
