1) Used to describe, or ask for validation, on an actual object which bears a dome-like resemblance to an aforementioned or predescribed primary template that has been widely accepted as THE Domeshape.
2) An exclamation of near highest order used to express a myriad of feelings from simple boredom, to fill the time, to extreme anger, possibly in an effort to, in a rather half assed and semi-polite way, ridicule the protruding belly of a pompous jackass.
3) A versatile expression used by chui's, yui's, tangy's, PEPPs, matayoshi's, chowi's and a select few others...often accompanied by a dome hand gesture... similiar to one acting as if polishing a curved surface along a horizontal axis.
Perverted Evil Playful Pixie
Pixies, as described in fantasy tales, are mischievous and prone to pranks. If we were to have such a pixie that had added emphasis on being perverted, evil, and playful, it would certainly be described as being extremely energetic and full of spirit. Hence I modified it to the acronym PEPP=PEP
Don't be fooled by her quiet front, she's really a PEPP.
