girls between the ages of 16-19 that are excessively overweight and have bipedal displacement issues, and waddle or spin/turn as they step. but in order to be slarge the girl must be exceedingly obnoxious and annoyingly outspoken. match that with the ignorance and disrespect to sit and wreck peoples couches or chairs or any other thing that their obesity would destroy.
the slarge's total being is so far gone that it affects the shape of sound they form in words, much like the sound of gigantic tubes flayling about with the wind almost whistling through
'oooohhh(any obese related stretch or mutation of words, jumbled sentence or sound)'
'oh man, i think slarge is coming, dont let her see us'
