look up any word, like bukkake:
 
1.
Acronym for "Laughing On The Inside A Little".

Used when texting with someone and they say something that just makes you chuckle inside - but just a little bit.

Use when LOL or ROTFLOL or even LOTI are too extreme for the level of amusement you are experiencing.

Can also be used to show a bit of sarcasm when you know the person wants you to laugh at what they said.
Someone texts you something that is mildly amusing, you reply LOTIAL
