In it's day, the net abbreviation for the words "laugh out loud" and "lots of love" were both used to express true feelings.
Let's start with "Laugh Out Loud".

It is normally used, quite obviously, to imply that statement is humorous, such as;
Person 1 : I just watched (insert funny moving picture).

Person 2: Lololololololololol!!!!!11111@@@

In this example, person 2 implies that he/she is laughing at the phrase.

It's now very plain to see that Person 2 didn't even care to read the said message.

Here are the new definitions, the redifined lol.

1. I didn't care to read what you took the time to write to me, so i blurted out lol, the word that is always on the top of my mind, always to be used on message boards and all that crap.

2. I listened, but your quote lacked any humorous content. I will pretend it did to make you feel good.

3. I have nothing to say that will be of real significance to this debate/conversation, so i will pretend i know what i'm doing.

4. I really don't care.

Lots of love, my personal favourite definition, has kept it's true meaning.

The only definition...

The sender of this slang is showing that he/she loves you.
It's a sweet way, to say Lol, but sometimes i think that the sender could express it a little more, because three letters is a little cheap.
Sad Person: My cat just died...

Mindless net-geek: LOLLLLL!!11111

Girlfriend (with a life): Bye, babe, LoL.

Boyfriend (also with a life): -Speechless-

And, if you were nice enough to actually read this definition, you're my favourite. Yes, you.

The ultimate in stupidity, its is a bastardization of the word lol (laugh{ing} out loud). It is used by only the most ignorant and desperate of users. Avoid at all costs.
