A dude who is quick to go ape shit and is easily pissed off without warning. This dude goes quietly about his day then goes wild unexpectedly. Similarly seen in nature when a real silver backed ape is lazing about within the jungle until some tiny thing unexpectedly sets him off. Stay clear!
Nick totally became a silver backed ape when he saw his old girlfriend with a new dude.
