commonly used in michigan's upper pennisula; this timeless insult is used when a swear word is inappropriate; (i.e. work, in the company of children, or great grandmothers)said in one fluid motion (one syllbal) BISH replaces the forever loved BITCH (see bitch) in a swearwordless insult.
Something douchebags say in place of the word bitch. It is either used because they are too pussy to actually say bitch, or because they think they are cool.
