Rolling On the Floor Laughing My Fu**ing Brains Out, in short ROFLMFBO, is an adaption of an ''old'' internet accronmym for Rolling On Floor Laughing. The integration of the second part, laughing my f-ing brains out, is probably originated from several animation shows. Like ROFL, ROFLMFBO can be used in a satirical manner.

ROFLMFBO is mostly used to emphasize how extremely funny something really is. Sometimes it is used in reply of the acronym ROFL itself.

when you've done something so cringe you can't stop replaying it in your head and it stops you from getting on with your every day life
