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.
