Poser Wall 

The Wall in Stores like Hot Topic that displays band T-Shirts, where posers will stare , reading random band names outloud in a poor attempt to seem Music Savvy.

Poser: "hmm They have The Misfits cool!! ohh i really like....*squints* Joy Division? *looks around store nodding head* (Quietly searches for a safe Fall Out Boy T-Shirt on the Poser Wall)"

Post-fartum expression 

The sigh of relieve and that silly smile a person has after letting out that gas that has been held in for so long.

Slightly changed term from 'Testees' Ssn1 when Peter lets out a huge fart that he thought was a baby and Ron tells him he's got post-fartum depression. Post-fartum expression is easier to relate to.

Possum's Haystack 

n: The gnarliest, nappiest, most tangled thicket of pubic hair known to mankind.

Many different species of animals may inhabit the possum's haystack, because of the multiple ecosystems grown over time.

Nobody really knows how people become inflicted with the possum's haystack, however, experts do believe that it could possibly obtained from little to no maintenance to the "under rug" for many, many years. The condition, however, is fatal.

Reginald M. Nooker was the most famous case of possum's haystack. He did not trim his pubic hair for 39 years. His hair follicles were so overactive that they did not grow long, but thick, and tough, and they curved back and around in every possible direction. He broke many chainsaws simply trying to find his penis.
