The outcome of an unshaven scrotum being squeezed until the veins stick out. The shiny skin is evident, as well as the pubic hair. This looks like what would appear to be a small hairy brain. Hairy monkey brains!
when on/in a moving vehicle and there is a very sudden unexpected need to stop quickly, panic monkey braking occurs. this is the kind of braking where there is a cold sweat generated that drips (usually down your buttcrack) that you don't feel until after you are past the incident (assuming you didn't hit whatever it was that you were braking to avoid).
i was riding my triumph street triple in lincoln park at night yesterday when a stealthy 200 pound dog bolted out into the street in front of me between two cars! panic monkey braking ensued, and i was able to avoid hitting him, but i *will* need a new set of underwear.
A component of female nature where a female who currently has a significant other establishes a emotional and physical relationship with a male of higher status unbeknownst to her current mate. Then leaving the current mate for the for the new male. Thus resetting the cycle.
Male #1: Wow Im surprised, my girlfriend of 2 years broke up with me and she already is in a new relationship 1 week later with the guy she told me not to worry about?!
Male #2: Sorry to tell you bro but she monkey branched. She was already "his girl" long before she ever broke up with you. She ended your relationship once that other guy was ready. She will do the same thing to her new boyfriends once another male of even higher status shows her interest.
