Shit Birds, Angry Birds, Dirty Birds ~~ you choose

	Your above average asshole that usually will do things to piss you off or screw you up so they may further their own perceived wellness. Often also does things not knowing how much they are a screw up but again generally fucks you over. That shit bird cleand up his leaves and they blew into my yard now hey thinks I'm the lazy neighbor.
	Comical but frequently used insulting military jargon generally used to denote a lower ranking enlisted person whose uniformed appearance and/or job performance is substantially unsatisfactory ('un-sat'). A person who can be counted on to screw-up the most simple of tasks, and generally not entrusted to handle much more than the menial. Also utilized among civilan population albeit with far less frequency and familiarity; does not resonate with same defamitory impact as when used in military circles. His shirt isn't ever tucked properly, shoes haven't been shined in ages and his haircut is barely within regulations-not only does he look like hell in uniform but he's terrible at his duties too, what a SHIT Bird!
	An uncommon insult that generally makes others laugh at the person being insulted. Commonly used insult in US Navy bootcamp in Great Lakes, IL. Named after those little friggin Shit Birds that hop around all day, just eating and shitting. Eat, and .... SHIT. Eat and friggin Shit. They never sing, always shitting where you're about to do push-ups and even if you happen to stomp one, they're not big enough to eat. Damn shit birds. Bootcamp company commander at 4am....
