look up any word, like bukkake:
A Rimsel is a hybrid of both a Rimmer and a Weasel. He/She embodies qualities of both terms and enjoys weaseling around whilst looking for anus holes to lick.

The gingery hair found on the face of weasels is still apparent on a Rimsel, as is the large snout.

Although a person can be called a Rimsel, the term can more effectively be used by essentially re-naming the person as 'Rimsel', see examples below.
Robin Williams is such a Rimsel
