Lolworthy should be used when someone or something has performed something which should be laughed out load to.
The word was invented by Robert Shaw when he was bored of using the lol phrase on MSN.
Ashley:Dude ur such a retard
Bob: Ha ha but your LOLWORTHY
something that you actually lolled at, or would have lolled at if you didn't feel like such a loser laughing when there was no one to hear
p1: ahh dans such a fag
p1:did you actually laugh?
p2:yeh it was lolworthy
Something funny enough for a lol. Of course when people say lol they probably aren't laughing out loud.
Person 1: "Have you been on lolcats?"
Person 2: "Yeah, it is definitely lolworthy"
