Posémon
Term describing the 'poser' Pokémon of the newer generations which wholeheartedly fail to capture the general spirit and imagination which represented the popular Pocket Monsters of generations I & II, and a few of III & IV. Often these Posémon are poor man's rehashes of well-known classic Pokémon, such as the lolworthy Woobat (Zubat), Purrloin (Glameow) or simply consist of something ridiculous like an ice cream cone which gains a scoop upon each evolution. (It's funny 'cause it's true)
Parf
Alternative phrase to parp, simply meaning a fart. Derived from a misspelling / misconduct of the word. The word doesn't differ too much in usage, although is mostly said for more comedic affect.
