Patented by TSN's Jeff "O-Dog" O'Neil, a "door open moose" refers to the act of leaving the bathroom door open or ajar during the act of "pooping". The term moose refers to the size of the donation.
"My wife is not impressed with me, I just did a door open moose". "Please close the door, no one wants to watch you door open moose"
