That's So Funny

Developed by a gang of street kids that were sick of putting up with lol. 'tsf' is a rising force in the internet slang directly substituting lol in it's various forms. Commonly used by the coolest people in the world, including the queen and ronald mcdonald, tsf is a hot one to watch and a better one to use.
