This slang word was coined by the infamous TheWineKone of YouTube through his frustration of the word "lol" being constantly used over instant messaging programs.
Short for “Thinking Out Loud.” The mathematical equivalent of LOL, which is recommended for students to do, as they discuss with others how to solve a math problem, or articulate which step in a math proof has led to a faux solution or contradictory result.
Math teachers and tutors ought to encourage their students to TOL, because this under-utilized or overlooked habit would help them articulate their mental processes, while allowing others to expose their faux or flawed reasoning, if any.
A person that is trying to be a tRolL, but has problems Reading and understanding the message of the person he is trying to troll; furthermore, the person has very limited knowledge of the art of the written word i.e., Literature.
This is the reason the letters "r" and "l" were removed from the word troll. Example: "He's just a tol".
