Greater than LOL, ROFL, LMAO, LMFAO and ROFFLES, Lolosaurus is perhaps the greatest e-way of saying "I find that funny and would wish to say so in a gradiose fashion" however if it were to ever be translated into a laugh it would kill the laugher.

lolasaurus

The only appropriate weapon to something that is so stupid it's funny.

The pop up said "If I close this window, they won't tell me who has a crush on me" so I attacked it with a lolasaurus
