really gay acronym used online which stands for

Rolling On The Mother Fucking Floor Laughing My Mother Fucking Ass Off

it's really quite sad when someone uses this term and it's a big indication that they are virgins and probably still live with there mom, and spend 17 hours a day playing runescape..
