Ice troll 

when you are drinking something out of a cup and one (or more) ice cube(s) blocks whatever it is that you are drinking, causing it to miss your mouth and go straight down your shirt.

I got ice trolled this morning when the ice in my cup blocked my mouth, which caused the water to spill down my shirt.

Socrates Troll 

A master of logic and philosophical debate who has nothing better to do than undermine your worldview for their amusement, causing you to want to punch them in the face, then force-feed them hemlock.

Congrats. You just poked a giant hole in my logic. You could've been a lawyer and fought for justice, but instead you're just a Socrates Troll. Your talent is wasted on your amusement and my annoyance, so yes, I am mad, Bro.

Share Troll 

A person who posts persistent negative comments about stocks and shares on boards and twitter.

This type of troll differs from regular trolls in that instead of attacking individuals, they directly target shareholders. They generally work in co-ordinated groups, have multiple identities and may be paid by a group of traders or a cartel. Their main objective is to spread malicious rumours in an attempt to get investors to sell their stock or create market volatility. There are several reasons for the emergence Share Troll activity but the main reason is to "shake out" investors in order to protect short positions. Trading rackets are known to protect their lucrative short positions by employing share trolls.

This company share is under severe pressure at the moment due to market sentiment. Many share trolls are out in force tonight on bulletin boards trying to get shareholders to sell up.

Barn troll

A barn troll is someone who has not been raised with a level of tact and/or has not established respectful and clean habits in life, such as flushing the toilet, observing regular personal hygiene and not acting like a seven year old in your career. Really, this can be used any time you want to confuse and insult someone at the same time.

I.e. slimans entire immediate family

Sliman: * Frantic hyperactive chatter *
Renner: dude you're a barn troll
