In the game Dark Age of Camelot, it's when a male toon kills a person and sits on his head. Usually the now dead person had pissed the player off in the past. When a female does it, it's called a "sheep-herder's special".
that's the dude that tried to assjam us, give him an asshat.
A hat, with a fireman's type of face shield, which protects you from coming into contact with "ass particles" from a third party.
The genesis coming from a story told by an lady who was angry that her partner was cheating. In order to get back at him, she cheated as well, and during that session performed massive amounts of annalingus. Afterwards her partner asked her if she wanted to take a shower before returning home. She said no. He then remarked, "well what if your boyfriend tries to kiss you when you gethome." To which she replied...."who cares!"
If her boyfriend had his asshat on, he would be safe.
"That girl is so dirty, I wouldn't touch her without my asshat on....."
"She was so nasty, even an asshat wouldn't protect you."
