look up any word, like fleek:
1.) Noun - The missing log of fecal matter sworn to be residing within the anal cavity when going to the bathroom. Long periods of pushing and grunting seems to have no effect on the release of a misturd, and such actions seem to have some health problems such as ulcers, heart failure, and eventually death. A common synonym that can be used is a misfire.
Guy #1: Hey man, you were in there a long time, what happened?

Guy #2: Oh, i had a misturd.

Guy #1: That sucks man. I hate those.

Guy #2: Me too. Me too.
