Semen, cum,
jizz.
A slang term, originating from the Jamiacan/West Indian slang for a gay man "batty boy," perhaps originating with the misbelief that homosexuals often wash each other in their own
semen.

"What's that white stain on your pants
Dan? It looks like you didn't clean up your
batty wash."
