Floor is lava

"Floor is lava" is a fad on CE. Inspired by the children's game Hot Lava, the fad involves the following: a user will create a topic designed to draw in CEmen with a misleading title and, in the original post, declare that the "floor is lava" (or some other variation). Users who have entered the topic must report what was burnt or why nothing was burnt.

Like all fads, it eventually became moddable after a while.
