Acronym for "when I
fucking feel like it." Useful as a
catch-all answer for when you're going to
get something done.
Boss: When are those floors gonna
get swept?
Employee: Wiffli.
A: When are we going to the store tomorrow, anyway?
B: Probably wiffli and not before.
I'll get to it wiffli, man.
Don't get all bent out of shape.
