Dead Moose is a form of horseplay usually participated in by a group of men. The term was made famous by the Eminem line:
"Sometimes I wanna get on TV and just let loose/But can't, but it's cool for Tom Green to hump a dead moose"
which references actor Tom Green humping a dead moose on MTV.

The game starts when one member of a group places their thumbs on their temples and stretches out their fingers, resembling a moose's antlers. The rest of the group follows suit and the last one to do so becomes the dead moose. The dead moose must immediately lie still on the ground, while the rest of the group dry humps them with vigour. The game is over when the humpers decide that the dead moose has been defiled enough.

A person that would seem like they would be great in bed, only to disappoint when the time comes by laying around and being utterly inactive.

Get the Dead moose's last shit mug.
A very graphic Canadian insult indicating that the person to whom the insult is being hurled it thought of so lowly that they should do this most disgusting of things normally as it is clearly something their character indicates they would consider normal practice. In other words, the person is disgusting and so are their habits.
esp. heard in rural Ontario when someone says or does a thing to anger their associates they would be told to 'go suck a big dead moose cock'. Also heard as a reply to another insult... i.e. if X says to Y 'your mother wears army boots', Y might be heard to reply with 'oh yeah eh, well your mother sucks big dead moose cock'. And on it goes like that until one of them gets a bloody nose.
