Tristana sound bug, constantly hearing teleport sound

A few days ago a Tristana on my team was constantly complaining about hearing this sound, i thought nothing of it at the time. I just play played a game as Tristana now and I started hearing the same thing. At first it kept making me paranoid but after the 3rd time of hearing it I remembered about the guy complaining a few days ago and realized it was just a bug.

So during the game I made sure to pay attention to when it happens and discovered every time I activated Tristana's (W) skill, you would hear the sound of teleport. Has anyone else been having the same issue? Because this is now 2 different cases of this happening.
