roflmaobbq

Acronym for "Rolling On the Floor Laughing My Ass Off Barbecue". Almost exclusively used to poke fun at overuse of stereotypical internet acronyms such as lol, rofl, wtf, omg, etc. If spoken, it is pronounced Roffle Mayo Barbecue. Use of this acronym may indicate its user is sick of having to endure all the newbs using the above acronyms, or could be meant in a more lighthearted way.

Newb: "Omg lolz! i pwned that ganker with a headshot!"
Newb-hater: "Roflmaobbq....."
