Rofalafel is derived from "rofl," and is another extension of the popular acronym meaning "rolling on the floor laughing." It was coined by Yula one day because she just comes up with brilliant ideas like that. Much like roflcopter and roflpotamus, rofalafel consists of the joining of "rofl" with another word which rolls off the tongue. It is the combination of "rofl" and "falafel" -- a fried ball of chick and/or fava seeds. Rofalafel is used to emphasize when higher than normal lulz have been had. It sounds like "roflofl," only tastier.
"...and then I jizzed in my pants."
