When you type /rank [username] on Showdown, what does the "T" mean?

Question

On Pokémon Showdown, when you type /rank [user name], it will show all points in each tier the player has played and it shows W, L, and T.
I know W = Wins and L = Losses, but what does T mean?

Also I saw some ranks of professional players in OU and they have W-396 / L-318 / T-3 and as you can see, T is really rare!

So I want to know what the T means and how it's possible to have one.

Answer 1

T=Tie

Just like W=Win and L=Loss, T stands for Tie.
You get a tie if both players forfeit or disconnect.

Why would they leave the game when the opponent already left? Losing points maybe..
Thanks! :D
