Ass Joint 

Bath tissue remnants deposited on and around Toilet rim. In extreme cases ass joints have been known to migrate to surrounding floor. Ass joints are created when inferior bath tissues are used on "rough" (many cases hairy) Anuses. The end result is a rolled tissue joint thats 420 for your 6:30.

I had no choice but to use the filthy public bathroom stall that was littered with Ass joints.

Several Joint Liability 

When a party is liable for all of the damage incurred by a third party after becoming excessively high on marijuana.

Jake decided to smoke a pack of joints, and, as all stoners do when they get high, he took a baseball bat to every car window on his block. Jake will be liable for the damage under the Several Joint Liability doctrine introduced by Justice Holmes in the landmark case Marley v. Jane.

Pregnant Joint

Impregnated joints are said to be pregnant because of their oblong shape. Pregnant joints are prone to running when not rolled tight enough or loose in one area.
