Get the the moment i knew mug.
A phrase used to let others know they've traded sides, i.e. committed treason. This word developed from the blockbuster motion picture 300.

The acts of treason committed by the hunchback traitor Ephialtes stem from his rejection to join the Spartan Military. His morbid anger leads him to join sides with the Persians, thus trading sides in 300.

This phrase is highly adaptable in modern day sense. Whenever someone you see commits an act of treason, betrayal, or pure stupidity, respond hastily with "I knew you'd trade in 300."
Let's say you call Shotgun and Pit steals it from you anyway. You're too borderline blackout drunk to even want to argue with Pit. So, instead of arguing with him, you simply say..."I knew you'd trade in 300."

1. Said by someone who has a very obvious unrequited gay crush on someone who remains oblivious to his flirtations. Usually said after doing the thousandth favor for him for free, despite massive actual personal cost.

A humorous reference to the epic line uttered by Jack Twist to Ennis del Mar (RIP Heath) in the film Brokeback Mountain.
Dude 1: Thanks for the coffee. You didn't have to walk through 600 km of hot dry desert, cross an ocean of razorblades, and defeat 10,000 dragons just to get me one.

Dude 2: Oh it was nothing. Anything for you. *stares longingly at Dude 1 as he sits down*

Dude 1: Why are you staring at me?

Dude 2: I wish I knew how to quit you...
