LOLROTF 

Combination of "LOL" = Laugh Out Loud; and "ROTF" = Rolling On The Floor.

I'm laughing out loud as I roll on the floor.

Lolrofl 

the act of laughing slightly more than rofl, but not as much as roflmao, funny enough to actually laugh IRL, but not enough to actually roll around like an idiot.

Man1: dude, my dog ate my alarm clock!

Man2: lolrofl, you fail!
