It's an acronym for Rolling On Lawn Farting.

Usually used by those people that change things around and all that as attempts to either confuse us or humor us. Either way we hate it and that's why you are here looking it up.
Someone says something on the Internet to another guy so he responds with a simple "ROLF" which causes the first guy to either pass it as a typo or ask "rolf?" so the guy says that he was rolling on his lawn farting.
