When a guy spanks or slaps another person with semen on his hand - i.e. just after masturbating.
This is a generally condescending move on par with
tea-bagging, and - if executed properly - causes considerable distress on the recipient's end.
Do not attempt this on someone that is physically
stronger than you because they will perceive it as a sign of great disrespect.
"John was being a real douche last night, so I
jerked it to a picture of his girlfriend and then spunked him in his sleep."
"Dude,
knock it off or I'll
spunk you."
