Tit Mule 

A mule of who's tits reach at least to the ground when the mule is standing straight up upon four legs. This term is often under-used, like tits that reach near to the ground. Also see "Half-Tit Mule" which is a mule who's tits reach almost exactly half-way to the ground.

The Mule 

the butt of a gun.
to "hit someone with The Mule" is essentially pistol whipping, but it should be noted that when hitting someone with The Mule only the butt of the gun is used.

"Bitch wouldn't stop running her mouth so I had to hit her with The Mule."

ass like a $20 mule 

A rancher in the old west wanted to only purchase a mule that had a large muscular hind quarter. Twenty dollars was a lot of money so a rancher would only pay that much for a mule that was well built. Used to describe a woman with a nice round ass made for "working".

Wow that girl has an ass like a $20 mule!

shopping mule 

Boyfriend, husband, credit card on legs or other that has been coerced into coming shopping for the purposes of carrying bags and/or paying for purchases.

I've been dragged all over town by my wife as a shopping mule and am now many pounds lighter. Thank God for The Boyfriend Chair!

Marsh mule 

A guy that calls girls swamp donkeys but is really hypocritically speaking about himself and his love for fat nasty swamp ladies. Often sleeps with any donkey with a swamp between the legs. Can be known as a desperate mule who has no care for the swamp and just wants to settle in a marsh with his piggish self. Can be found at bars scoping swamp donkeys.

That marsh mule shouldn't be calling any swamp donkeys out with that mug of his.
