A term used when a person has totally
owned something, or done really
well. Usually used in reference to a test, sport, or other personal trial. The term can be reversed to imply
failure.
"Dude, how did you do on that test?"
"I totally anally penetrated it, I got a 99%!!"
or:
"How was your
hockey game?"
"Ugh, we
lost 0-11, the other team totally anally penetrated our goalie!"
