Man, Marie said she had a headache and left my place really early last night. I had to go shoot the moose to take the pressure off.

The act of having sex in general, inspired by the movie Brokeback Mountain, where as one of the main characters fires upon a moose before engaging in hot cowboy mansex.
We were caught Shooting the Moose at the family reunion, that sure didn't go over well with grandma...
