ROTFFLMFAOWTIMEBBQ

Rolling on the fucking floor laughing my fucking ass of with tears in my eyes barbaque

This is one of the more extreme hybrids of the basic "LMAO" and "ROFL" archetype.
It is also so long that no one practically uses it.
I advice against barbaque-ing your eyes.
What are you doing here anyway?

"OMG when he fell it was like you know like the like funniest fall ever and I was like ROTFFLMFAOWTIMEBBQ!"
