The 'crack sweat' theorem

Theory identifying the cause of a consistent, vague odour of fecal matter i.e. absolute shit, in some.
The theory states: initially, said person, has failed to properly wipe their crack fully, thus leaving remnants of shit (dingleberries). With strenuous activity and/ or heat, sweat develops within the ass crack. This sweat mixes with the now encrusted and dried fecal matter, bringing it back to life, creating a noxious fume- comparable to shitting your pants.

Proposed in 2006.

Turdpreet: 'Yo, geeza, I swear i can smell shit ya' know; like full on shit!'

Shitinderpal: 'Yeh geez, me too. I smell it all the time in this lesson, it's probably (insert name here), 'cus he's so fat- he properly can't wipe his arse properly!'

Turdepreet: 'Oh yeah, that's a good point, that ties in nicely with the 'crack sweat' theorem (2006). That explains it!'

Shitinderpal: 'Oi (insert name here) you fat twat, go wipe your bumhole son, you need some bleach in there, smells like hardcore shit!'

plastic crack 

A semi-pejorative term for polystyrene plastic figurines and miniature model kits made for tabletop role-playing games and wargame simulations, particularly the popular Games Workshop Warhammer Fantasy and Warhammer 40,000 lines. The "crack" designation applies in that fans of these types of games seem "addicted" to them like a drug, and crave buying, assembling, and painting the models, spending large amounts of money and time in doing so, and anxiously await the latest, most finely-detailed releases.

Also used self-effacingly and endearingly by samesaid fans of these games with a good sense of humor about their "addiction".

"Oh, man, it's the new Leman Russ Demolisher kit, and it comes with all the main cannon variants...sweet, sweet plastic crack!"

"Garth came into the comic shop this afternoon and dropped over $300 on plastic crack. Poor, sad bastard...he must live on soda crackers and peanut butter."
