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.
"I was in the club last night when some silverback drove me off the bar."

"Gotta watch my step... my girlfriend's ex is a silverback."

The emotional and intellectual antithesis of a gentleman.

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.

Silverback is when a mentally retarded person gets furiously enraged and gains superhuman strength.
The retard was so enraged that his ketchup wasn't a turtle, that he went silverback and flipped the entire table over.

an older african american male. because just like the actual species, it's pretty rare to see one alive and in the wild.
if you plan to go to Roscoe's Chicken on a weekend, either get there early or be prepared to have to fight your way through swaths of silverbacks if you want any waffles.
