A word that can be used in almost any situation and as any part of speach as an exclaimation of enjoyment. but it is mainly used to describe a non-extant being.... the skimmy or the skimmies. These "things" tend to preform a action called "yow"ing.
1: That movie was skimmy...
2: The skimmies are yowing
The clenched butt cheek walk/run one finds themselves making to reach the nearest toilet before raining a gush of explosive diarrhea in their pants after eating too many chimichangas (or even one funky one).
Got drunk last night and ate 3 chimichangas. Seemed smart at the time, but woke up this morning with the Chimmy Shimmy. Damn near crapped myself!
