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.

Get the Internet trollmug. 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.

Get the Troll Beastmug. An off shoot of motor boating, but with differences. It's when a man takes another man's penis, holding it like a motor boat throttle, and rubs his face and lips across the reciviving man's testies and sack.
The kindly mustachioed gentleman introduced his good friend Tom to the joys of Motor Trolling while giving him copious amounts of oral pleasure. Tom was pleased.
