Posnered 

When a bowl of marijuana has a few remaining hits before being kicked. Weed connoisseurs will empty the bowl rather than continue to smoke ashy weed. Average or younger pot smokers will typically continue to smoke a bowl that is posnered until it is completely kicked.

I was really drunk and smoked it till it was kicked. I usually repack it once it's posnered.

Posner

Taking a big, fat, hairy penis up the nose. A Posner typically happens when the person on the receiving end of the penis is tired of having their face jizzed on, and would rather have their face jizzed in.

Damn, she asked for a Posner since her jaw was tired and her face was covered.
