The art of appearing to be productive at work without actually doing anything of any value. In its truest form this involves loud, screeching equipment, foul language, and blaming everyone/everything around the half-asser in a covert manner, i.e. running to the head boss and ratting on everyone else while simultaneously kissing the head boss' ass.
Employee 1: Damn that Rocky! He's such a pussy!
Employee 2: Nah man, that n#%&a's perfected the art of half-assmanship.
