Diet Coke and Mentos

Something half of my definitions involve. See also sex.

When you take a 2-liter of diet coke, unscrew the cap, drop in a few mentos and close it. You then take the bottle and
1) Leave it somwhere on the ground to explode like a volcano
2) Throw it hard at the ground to make it explode and propell it in a certain direction
3) (This is a dick move) lube up the top of the cap, approach someone from the rear,(willing or not, they could have lost a super bowl bet, came last place in the bracket group, lost a game of rock paper scissors or is just a bitch) shove it up their ass and retreat to a safe distance to watch.(WARNING, that shit is dangerous)

A challenge where you put a bunch of mentos in your mouth and trying to consume a 2 liter bottle of diet coke spilling as little as possible. The chemical reaction produced by the coke interacting with the mentos causes it to burst out causing people to spill coke while consuming it.
