KILF = Keif I'd like to find. A KILF hunter is someone so broke, that when they want to smoke some bud they have to hunt through every old baggy, every crevice around their car, and in their bed as well as other awkward places to find some shake. No one wants to admit to hunting KILF, but it happens... and hopefully it doesn't happen to you.
Nigga you so broke you've become a KILFhunter just to blaze. Get a fuckin job!

My Friend: Oh Yeah!

Starbucks forgot to give Levi a kilfer with his coffee so he burned his hand, dropped his coffee in his lap, which in turn burned his junk.
If McDonalds had provided kilfers with their coffee in 1994, they would not have been sued.
