RALFTOMATO is a derivative of ROTFLMAO. It was derived from the overuse by some of the ROTFLMAO acronym and is now widely used in internet chat rooms, message boards, instant messages and e-mails.
RALFTOMATO is a sacred acronym and is not to be overused like ROTFLMAO is. RALFTOMATO is to be used to show a true feeling of laughter.
(insert funny joke here.)
