LOIS stands for Landmine Of IdioSyncrasies. Someone that others perceive to have many different awkward or weird behaviors. So basically everyone.

An subtle way of trying to convince someone that another person's thoughts or behaviors should be viewed in a negative way.
Don't be a LOIS, you are behaving weird.

He is a LOIS, sipping his water so loudly, shaking his leg when he is nervous and always forgetting people's names.

Whichever you like:

1. Akin to LOL. Meaning "Laughing on the inside."

2. LOL's cousin-brother. Laughing On Inside.

Code for each first letter underlined:
<U>L</U>aughing <U>O</U>n <U>I</U>nside.
Loi means laugh on inside

Ex: When you get a text and really laughed on the inside, and don't want to lie by saying "lol"

A powerful girl or boy who never gives up on their Dream! A cute girl or boy with amazing eyes and hair. Always loyal and always takes care of people even if they aren’t her or his friend. If you are friends with a Lois or even know one you are a very lucky person. There are not many lois’ in the world so treat them right! Lois’ don’t give up on there crush they will never move onto another person beacuse there crush does not like them. She will continue to try and win his/her heart. She is a loyal friend that inspires people to be kinder! They are very curious and love to explore and wish that they were in a real life fantasy. Lois’ normally day dream. Also normally like fantasy books,film or shows. They will obsess over enything they like! Be a Lois
