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.

This is when you engage in any adventurous activity exclusively outdoors, in most cases hiking, and you spark during the expedition.
1. "Ay Darnell you trying to go hiking on that trail today?"
"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."

in volleyball, a spike is what you see when 1 member of a team pounds the shit out of the ball into the opposing, team's side of the court. May or may not result in a point.

A particularly frustrating and violent (and usually loud) skype conversation. Usually with a grandparent or someone unused to modern technology. It doesn't start well and ends even worse.
Child: Hello? HELLO? Grandma can you hear me?
Grandparent: HELLO? HOW DO YOU WORK THIS THING? ARE WE SPIKING?!
Child: Grandma click the volume button!
Grandparent: WHATS GOING ON?! I DON'T SEE YOU. CAN YOU SEE ME?! SPIKE ISN'T WORKING!
Child: *mimes turning up volume*
Grandparent: THIS IS JUST RIDICULOUS. I'M GOING TO CALL YOU!
Child: Wait! Wait! All you have to-
Click.
