The action of having sex with a girl on her period and, subsequently, slapping her
on the forehead with your, now blood covered, penis. This action causes the girl to look like she was
brutally bludgeoned, but, in fact, has just engaged in some
good ol' fashioned fun.
"Did you see those pics of
Sylvia?! She looked like she got her head
bashed in!!"
"No way man, she was just given the old
bloody bludgeon. Look, shes smiling in the picture."
