When someone uses the word 'like', either written or spoken, as a thought-filler.
I was like listening to these two girls on like the bus, one day, and the first girl was like talking about a guy she like went out with and maybe she like likes him but doesn't like know for like sure and then the like other girl was like 'Yeah, I know what you like mean', and then I like started to like lose the will to like live and like the next think like I knew, I saw like the floor like rushing up towards like my like face.
