My current theory is that I took damage from a ricocheted bullet from my gun while I was pressed up against the wall holding W and as I jumped the damage caused me to get launched forward.

I think I was holding W while spamming M1 and then I jumped right before I shot forward.

I don't know if this is a known glitch or not but I thought I would share it here just incase anyone finds out how to replicate it or make use of it. I had cortical scaledown, angular advantage tactical munitions, composite helmet, and speed enhancer total organ package with the full damage ZKZ.
