keybanger 

A keybanger is to coast along in an manual carby'd car with the engine off pumping the go pedal 3-4 times then with the car in gear dropping the clutch causing the car to 'roll start' causing a great bang to show you mates you need a new muffler.

OMG I shouldn't have done that keybanger, I need a new muffler now eh uleh?

keybanger 

A keybanger is a person that has limited success with their sexual escapades in real life, and therefore takes out their sexual frustration online, via trolling, tearing successful people down, or otherwise critical posts. They more vehement their postings, the more virginal they are likely to be.

Non-virgin1 - These kids on 4chan are pretty pathetic, eh?
Non-virgin2 - Yeah, these keybangers should get out of the house and try to bang a girl instead of banging their keyboards all day.
Non-virgin1 - Oh well, more hot tail for us!

keybang

turning off ignition (usually in a stickshift), let it turn engine for a second or two, and turning it back on for a cherrybomb-like report! Works best when you're beside a pedestrian!
Expect to replace your muffler...

Kabangers 

When two mens testicles bang together in the act of double-penetrating a woman. Reminiscent of the 1980's fad toy Kabangers.

Those two dudes were playing kabangers on that porn actress.

When the Karma boomerang of life hits you in the ass and all is right in the world of those you have screwed over.

Sean looks so happy. Oh, that's because his ex-girlfriend who cheated on him with his bestfriend got kabangeranged when she found out his bestfriend gave her crabs.
