The hee hee girl is a highly flighty, social creature that tends to travel in packs, or gaggles. Their habitat of choice will be the shopping mall, high school hallway, nightclub or other socially-charged environment. They tend to adorn themselves with rather dull yet rarified plumage with prominant brand markings, which they procure at great cost. This showy display of disposable wealth serves as a symbol of status based on the very banal and superficial standards of their kind.
Because she has adapted to wasting all her energy on the cultivation of her outward appearance with little time devoted to the inner life of the mind, the hee hee girl is among the least intelligent and most simplistic of all the human organisms, and should generally be avoided.
alternate spelling/prnounciation: tee hee girl
astute passerby: Heads up, there's a gaggle of hee-hee girls at twelve o'clock.
