TDMer

A person who plays Sea of Thieves, but only plays the arena mode. In this mode, all they do is go to a fort and fight other players on the island. You can tell someone is a TDMer if in the arena lobby they spam the text "I am on the island!". They can't realize and accept that the game wasn't meant to be played that way, and always bitch about the hit registration. They also most likely will be cheating and still brag about winning, or if they lose DDOS you. In real life you can smell them from 50 feet away and they don't leave their mom's basement, regardless of age.

Guy 1: That guy is a TDMer, he's spamming "I am on the island"

Guy 2: Hope he gets better soon.

T.D. unit 

The T.D. unit is a new unit to enter the SI system of units. The T.D., otherwise known as the Toan-Dang, is a way of measuring stink/pong levels of someone or something.

A T.D. unit gives you a way of measuring odours. 0 T.D.'s indicates a neutral atmosphere, where as the definition of 1 T.D. is the peak of one's body odour. 2 T.D.'s would be twice as worse and so on. 4 T.D.'s is critically bad where 5 T.D.'s is death.

TDSBC 

A spoof on the MSNBC liberal media network name in which the first three letters are replaced with “TDS” which is short for Trump Derangement Syndrome, for the network’s obvious bias against the 45th President.

Don’t watch TDSBC, all they talk about is all “hate Trump” all the time.
