Buck Nanners - Is the act of going nuts and or crazy in a situation. It can also be used to describe something that is perceived as crazy or hilarious. It is a slight adaptation from the word nanners which is derived from calling something or someone bananas, which points to the fact that something or someone is crazy or "bananas". The buck comes in to give it that extra push to refer to a crazy "buck" just jumping around and going crazy, goring people with its antlers. To at which end people are just astounded at the craziness that has been witnessed and are at a loss for words. This can be explained by using the phrase buck nanners.
Dude, did you see that guy last night at the bar?
Oh yeah, the one that took 21 shots for his 21st birthday?

Yeah man, he stood up on a table and pissed on the floor, then puked all over that bachelorette party.
