moosemove
Otherwise known as "pulling/doing the moose", the "moosemove", is an ambiguous practice, and is most common among inexperienced men during the art of sexual practice. It is usually defined as mistaking the anus for the vagina or clitoris, so is usually "pulled" during foreplay or "doggy sex".
"Dude, he totally pulled a moosemove on her, and that's not the funny part! She was too embarrassed to complain, and didn't tell him until 10 minutes in!"
