1. A very Hot, average and superficial person who always loves talking to girls, you may find a Twils playing with your 6-year-old daughter near the playground, this is because Twils really love to play with children and act like them in general
Twils often grow their toenails very long in order to use them as a weapon in case someone confronts them, this includes Taiwanese police and neos.

2. A word often called out loud to protect yourself from very annoying girls, the word instantly gets rid of annoying 2005 brats and thots in your friendly Taiwanese neighborhood, the word is also very feared by children, especially girls, so if you have a kid, experts advise not using it near them as it could cause them to abandon your home when they grow older, become addicted and act as dangers to society.
Example:
2005 kid: yo Youtube Rewind 2018 is awesome!!!
Boy 1: Twils
2005 kid: *runs to mother*

Example:
Mother: oh boy, my son is a Twils, what should I do?
Psychologist: I strongly advise Euthanizing him if the issue persists

Example:
1. Kid: My classmate is such a Twils, talking with the opposite sex everytime
2. SWAT Officer: Don't move or ill shout it out loud!
