A beautiful girl's misspelling of LMFAO. It means Legalizing My Rough Quilted Ovaries. The word has become wildly popular amongst internet fiends and hax0rs. It started as a typo, and became a trend for most to use. LMRQO. Ilu.
Robynn: Dude, lmrqo!
Alisonn: LMFAO @ LMRQO!
Robynn: Shut up, it was a typo.
