LMFAO was an American hip hop-electronic dance music duo consisting of uncle and nephew Redfoo and SkyBlu. LMFAO's members were descendants of Motown Records founder Berry Gordy, Jr. RedFoo and SkyBlu grew up in the affluent Los Angeles neighborhood Pacific Palisades, where they formed the group LMFAO in 2006 and later became part of the electro house scene. LMFAO started building a local buzz through its shows and radio play. In 2010, it was featured on David Guetta's smash hit "Gettin' Over You", which charted all over Europe and the U.S., including reaching number one in the UK Singles Chart.

LOL or lol, an acronym for laugh(ing) out loud, or lots of laughs, is a popular element of Internet slang. It was first used almost exclusively on Usenet, but has since become widespread in other forms of computer-mediated communication and even face-to-face communication. It is one of many initialisms for expressing bodily reactions, in particular laughter, as text, including initialisms for more emphatic expressions of laughter such as LMAO ("laugh(ing) my ass off") and ROFL (or its older form ROTFL; "roll(ing) on the floor laughing"). Other unrelated expansions include the now mostly obsolete "lots of luck" or "lots of love" used in letter-writing.

LOL is an acronym or abbreviation for "laughing out loud" or "lots of love".
