Lmaooo

Laughing my ass out of orbit. Variation of lmao, where instead of just off, your ass is launched out of the hemisphere by your laughter.

Person 1: aren't you glad I didn't say banana?

The ultimate Flat Earth argument, if used, completely nullifies the use of any sort of logic or reasoning in support of the globe.

Logical Human Being: The Earth is round, we have significant bodies of proof in support of this, as well as overwhelming evidence against Flat Earth and nearly all other surrounding theories.
Flat-Tard: LMAOOOOOOOOOO room temperature
Logical Human Being: *Breaks down mentally as every bit of logic he has ever known is rendered useless. Dies.*

Lmaoo is an extension of Lmao, which means 'laughing my ass off'. Lmaoo is to be used when one is more entertained than a lmao situation, but not as much as roflmao situation.

Adding more o's adds to how funny one finds the situation.

Person 1: z0mg i r batman
Person 2: na na na na na na BATMAAAN!
Person 3: wtf? lmaoo!

lmaoooo 

lmao for people who are too excited to use not just one extra o, not just two extra o's , but three whole extra o's. Usually used when texting. Tends to be used when someone thinks something is funny enough to keep their finger over the o button to emphasize the funniness of the situation.

Rob: Hey, do you want the new cd?
Bob: Yeah that would be great.
Rob: See deez nuts!
Bob: lmaoooo
