Quantum Headspin

When you have a boner and lay down flat and start to spin on your peepee head and eventually you spin so fast that quantum mechanics break down and spacetime disintegrates.

Bill: "Hey man, I've been doing the quantum headspin alot lately. It sure does hurt!"
John: "What the hell is quantum headspin?"

Headsplosion

When you cause someone's head to explode by any method.
Examples:
Ganondorf's side special in Super Smash Bros. Brawl
Getting a head shot with a high caliber sniper rifle or shot gun.
When a chestburster Alien gets lost and pops out someones head.
Sticking c-4 to someone's forehead with Snake in Super Smash Bros. Brawl.

Headsplosion is the best way to finish people off in stamina mode

I got an awesome headsplosion with my 50-cal

Ewww, that little alien just splattered his brain with a headsplosion
