What does "to wilf" mean? Apparently it means to browse webs pointlessly but I can't confirm that anywhere. Is this even an English word?
It's an acronym that means "What I am Looking For"/"What am I Looking For". Also, it's an inappropriate term comparable to MILF, so I'm not sure I'll be using it anytime soon myself.
Same as "To nick", in the sense of "While you were in the shower, I wilfed one of your cigarettes".
