They love Mexican beer, Chipotle and energy drinks. They tend to wear shorts, flips flops, jersey's/wife beaters, SPY type sunglasses, straight billed hats or their hair in some "clever bed head" style. The most devoted ones will rock the soul patch. They will covered in enough AXE spray to make you puke and will constantly be texting hussies on their Droid or IPhone. They will drive their black lifted F-150 at a constant speed of 50-60 mph through every residential zone and will burn out at every red light. Avenged Sevenfold will be blasted at a deafening volume while driving.
Lastly, everything and everybody will be "gay" or be a "total pussy ass fag." Additionally, school is to be despised. The only appropriate conversations are: how much head and/or pussy you get or are going to get, sports and how much it sucks to have work 5 hours for your dad's landscaping company this weekend even though you'll just boss Mexican's around and get $300.
If you spot one of these creatures, do not be alarmed. Simply point, laugh and go about your business. They are simply overgrown 14 year spoiled boys that will never grow up. More than likely they will get arrested for domestic abuse, committing a hate crime or get caught cheating and have half their assets taken away in the divorce.
It's a slang term of endearment that works interchangably with the word "Bro"
