lol
Lol is an abreviation of "Laughing out loud".

Although many people commonly mistake it as "Lots of love". This can be quite confusing.
Laugh out Loud:

Person 1 - "My cat ran into the wall the other day"
Person 2 - "Lol"
Person 1 - "Lol"

Lots of love:

Child - "Im at school mum/mom"
Mother - " Ok have fun! Lol"

Lots of love which is mistakenly thought to be laugh out loud.

Person 1 - "My dog was put down today :("
Person 2 - "Aww lol :("
Person 1 - "WHAT THE F*CK IS WRONG WITH YOU!!"
