imp
An imp is a small mischevious demon-like thing who wears a multicoloured hat of doom, and has the propensity to lick people. Suspected to have jedi-like powers, these "imps" produce small furry mammals when poked by ninjas, the colour and species of which depends on the individual ninja and imp. The ubermammal in this particular case is the orange hamster, which has the inherent ability to dance in a 50s swing style to any kind of music, particularly metal. But despite popular belief imps do not like to sing, but are particularly fond of randomness and pickles.
imp + ninja + *poke* = dancing orange hamster!

important, impossible, impressive, improbable, impartial, impatient, impolite...etc.

Basically you say "that's imp" when someone tells you something and you don't know how to respond. This lets the other person decide what he wants it to mean.

Most often is used to mean impressive.
"I climbed Mt. Everest today"
"that's imp"
(did he/she mean important? impossible? impressive? improbable?)
