ROFLTSO is an internet acronmym for Rolling On Floor Laughing, Tongue Sticking Out. It's an overjoy laugh while tongue is sticking out, teasing, making fun of or joking around.

Related to ROFL, a ROFLASM means both to laugh so hard it comes close to orgasmic in its quality, and also literally abbreviates the phrase 'Roll on the floor laughing and shat myself'.
