ROLMFAOPAOTFBILTH
ROLL OVER AND LAUGH MY FUCKING ASS OFF AND PUKE ALL OVER THE FLOOR BECAUSE I LAUGHED TOO HARD, in addition to LMFAO (laughing my fucking ass off) and ROFL (rolling over fucking laughing), this is used when things are so stupid they're funny.
I ROLMFAOPAOTFBILTH when people lock themselves out of their apartments and break in with a nail and debit card.
