Acronym for "Rolling On The Floor Laughing Because We Are Trying To Make A Regular Expression Turn Into A Non-deterministic Finished Automaton", often said after a day spent trying to do something nerd without result but have watched some vids on youtube.
<Guy who meets nerd friends>: Hey nerds, why are you laughing in front of a pc?
<Nerds>: Rotflbwattmaretianfa, we would have loved to finish our nerd project, but this banana dancing on Peanut Butter Jelly Time is very very weird!!!
<Guy>: (Making a "L" with his fingers on his head) Losers.
