silver backed ape 

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.

Silver Back'ed 

Silver Back'ed named after the Silverback gorilla, is a sexual act of having anal sex then ejaculate on your partners back then messaging the semen on the entire back while rapidly thrusting your penis balls deep in both the Vagina and the anus switching between each.

Jerry: Max, man I totally Silver Back'ed Jennie last night!

Max: Dude that fucking kick ass!

Jerry: Hell yeah, am about to did it again tonight with her sister!

My girlfriend got really mad when I tried to throw her a backdoor slider last night.

Backdoor Slider 

When a man makes love to the crevice of a woman's butt by sliding his cock between her cheeks until he blows a romance explosion onto her back.

guy 1: "Dude I gave that bitch a backdoor slider last night!"
guy 2: "No way bro!"
