[k-krack]

I use it lot's, but that's just 'cuz it's become basically a way of saying something is relatively amusing, except not very... (easier than saying "relatively amusing, except not very...") Most of the time I say "hahahah" or "ahahaha" and even sometimes "hahahaaha". Sometimes, I make an error in finger placement, and get a "jajajajajaja". Rarely, though.
