Similar to 'LOL' meaning laugh out loud, however most people do not laugh out loud when they write this, so 'Linowabgas can be used as an alternative to 'LOL.' It simply stands for 'Laughing inside not outside with a big grin and sniggering.'
This is a more honest alternative to when people misuse the term 'LOL.'
Linowabgas man, you make me laugh!!
