The Floor is Lava 

1. A multiplayer game in which one person yells, "The floor is lava!" and all other players must comply and find higher ground to get to. Anywhere but the floor is safe and if players stay on the floor, then they are painfully burned to death. The floor becomes safe only when the player that called "lava" recalls that the floor has solidified and is safe to walk upon.

2. An utterance that causes absolute havoc when shouted. The equivalent of yelling "Fire" in a crowded theater, but perfectly legal and much more fun.

"When my friend yelled the floor is lava, I jumped on top of him to save myself and he burned to death."

the floor is wet 

A slang in prisons across US that is implying on nearby guards that are coming to search and/or check on prisoners. It's used between inmates to warn each other of upcoming possible guard.
Is also refereed to as "the floor is soaking wet" or "the floor is really wet" which means that C.O.'s know something is up, and the inmates should really hurry up with covering up any possible "unacceptable or illegal actions".

*THE FLOOR IS WET* screamed an inmate as he warned his inmates from possible danger.

The Floor Is Lava 

The most epic game in exsistence. Involves to or more people. The game is started by one person shouting that "The floor is lava!" After that, all people surrounding must find higher grounds (chairs, couches, pillows, younger siblings) to save themselves. If you touch the ground, you die. The game can be started anywhere, and is often fun to play in crowded places, such as the mall or the movie theater.

"The floor is lava!"
(everyone screams and jumps onto chairs and old people)
