A cousin of bitchass, with generally the same meaning. A little softer on the tongue though. You can use it instead of "Shit" or "Dam" too. You only hear the "Bia" and "sssss" when you say it fast so it's fun to say it. If there's more than 1 biatchass, then you say "Biatchasses" but pronounced Biatchsssszzzzz Kinda cleans the tongue..
You fucken biatchass, shut ya biatchass up.
