See this is a rather complex matter. There is to the extent of my knowledge there are three definitions for chaffe.
1. There is the literal term for chaffe which is a rash induced my skin rubbing skin generally in the area of the crotch and or buttocks.
2. There is also a definition used interjenctionally as an
irritation. Ususally caused by a broke friend.
3. Also when the night is
in full swing and you
couldn't be happier...That state of euphoria can also be described the final definition of chaffe.
