To “go silverback”: to fly into an intense and sudden rage which might involve contortions of the face, grimaces, a roar of anger and raised fists. After attacking and at least attempting to land a few punches, the rage recedes and the person often goes in a subdued and slightly embarrassed silence.

A douchebag of immense size and exceptionally limited intelligence, so called as he is often leading a group of similarly ill-tempered proto-humans, which often results in displays of aggression. Physical descriptions vary over time due to the fascinating lack of taste amongst the sub-species (though one common trait seems to be the love of male necklaces know as "chains"); the modern variation of the silverback is distinguishable by the sloping forehead, stench of day old AXE cologne, fake bake, and gym membership swipe key; he is recently known to wear Ed Hardy clothing.

The emotional and intellectual antithesis of a gentleman.

an older african american male. because just like the actual species, it's pretty rare to see one alive and in the wild.

a state of mind where a person loses all human inhibitions and becomes a silverback gorilla. this is usually triggered when the potential silverback is subjected to intense clownage. indications of this phenomenon include a gorilla looking face and body and movement using all four limbs. extra body hair may appear and the silverback may slur some obscenties and make vulgar gestures. the phase only lasts about one minute, after that the silverback starts to laugh as though trying to play it off. also used as simply 'silver'. the first documented case of silverback was Geoff Hynson at Purdue University.
Oh shit! Geoff's about to go silverback on our ass!
Watch out, that bitch is known to go silver.
