1% Chance

''Uh-- BOY. Look at this crit chance! (wheeze) Naaaaaaaaaahhhh, dude.''

When an event has such a ridiculously low chance of occurring that it virtually becomes impossible. This can apply to roles who Roll A 1 winning, certain UnTrashes' plays not being played, or meta events happening, such as the Innocent in old horror movies showing any form of intelligence. This is one percent away from becoming Nevar Evar, an UnTrash in which any given event occurring is entirely impossible. The near opposite of this UnTrash is 100% Chance, which is very self-explanatory.
