one way 

In the game "Counter-Strike: Global Offensive" In HvH specifically, A "one way" or a "one way wallbang" is a wallbang that is only wallbangable from one side. Meaning you cannot shoot back at the person in that position. A "fake-duck one way" is an angle that is made into a one way by using the fake-duck cheat.

I'm hiding in the one way because I don't know how to win otherwise
