To knock an airborne character downward at an angle such that the character has no chance of making it back to the stage. Used in the Nintendo Classic Super Smash Bros., and its sequel SSB Melee, to define all such moves. Also known as a Meteor Smash; however, certain moves that spike aren't classified as Meteors, such as Fox's Shine Spike, in which he uses his reflector to knock an opponent downward. Very 1337.
Falco has mad spiking skillz. His down+a has arguably the greatest knockback in the game, with no delay.

"Fuck that son let's go spiking. You bring the socket i'll bring the kush."

2. "Hey Sun-Choo, you wanna go hike the ridge trail at the Sourlands? It's supposed to be nice out."

"I'm only down if we go spike the Sourlands."

"Deal."
