To go absolutely and uncontrollably crazy both mentally and physically, akin to a gorilla fight. The outbreak usually ends within minutes but results in massive amounts of property damage. May also refer to:
1. The mating practices of gorillas during mating season, where competition leads to fierce, testosterone-fueled fights over dominance of the region.
2. The establishment of territory by the use of excrement.
Not to be confused with going ape shit, which refers more to the psychological attributes of the act rather than the physical intimidation.
My roommate is going gorillas flipping beds and intimidating guests.
