They are users on the internet (often found on youtube) that like to seek attention by starting arguments with other users. They also like to belittle you just because you commented something. They would also try to get you to react to them so that they can turn a lot of users against you or get users to attack you.
Here is an example:
User: I personally believe that minecraft is better than fortnite.
internet troll: Wow, you type like a 2 year old and your a baby because you like Minecraft better.
user: Stop talking trash because your typing is worst.
---internet troll edits comment---
other user: +user just shut up already and you cant tell people that their typing is worst.

A person that aggressively searches for companions of the opposite sex with no real sense of discernment, tending to be both unoriginal and uncool. Their approach is to bait many in hopes of catching one unsuspecting prey.

A person who overtly rubs a big loss in the faces of the losing teams fans; via social media, comments sections, ECT... despite the fact that they are (obviously or admittedly) not a fan of the winning team.
"Adam has always been a Dolphins fan, but the only time you here him talk about sports on Facebook, is when the Patriots loose a big game and he rubs it in our faces"
"What a sports troll"

Also known as goat troll or super sayain troll, he’s a tiktoker that dick rides dragon ball z, hates on Naruto 247 and throws a hissy fit when someone doesn’t like his favorite character Sakura going as far as calling people misogynistic for not liking his favorite character Sakura. He has posted videos saying “if someone calls your favorite character/show trahs ignore them it’s their opinion”. he tells others to respect his opinion when he calls Naruto trash but when someone calls dbz or Sakura trash he gets mad, this shows his very hypocritical tendencies. He also is know for his frequent opinion changes switching his top 10 list every 10 hours. He also missed on every post.

A troll beast is the name given to the ex(s) in your life that makes you want to vomit nonstop when thought about. In most cases you were under the influence of SOMETHING the entire relationship. These exes are usually obsessed with you for a good amount of time after you leave them. Nobody should be held accountable for these relationships because they are usually just a practice round for a real relationship. If you've had a troll beast in your past, you are most likely now in a fabulous relationship with you new, handsome/beautiful bf/gf...while the troll beast.... Is not.
Friend: Good God... THAT is your ex??!
You: Yes.. That God awful Troll Beast is my ex. But in my defense, I was drunk the entire relationship.
