An arrogant person or textrovert that hides on
the internet(their shell)to purposely harass others by saying hurtful and abusive things to others, but when they're stripped from their shell, they tend to be scared and bitchy
in real life because of how vulnerable they feel without their shell(
the internet).
"These trolls are such Neturtles, they always think they're superior to
everyone when it comes to being on
the internet. But I betchu they're a bunch of little pussies
in real life. LOL!!!"
