Only in Battlefield

A grenade launcher in Battlefield makes an odd sound, that can be described perfectly with the onomatopia "boop". Using a grenade launcher, underbarrel or even the Revolver grenade launcher.

Said whilst using the gadjet, in sync with the weapons firing.
Boop! *reload* Boop!

I just booped the shit out of that sniper

I just got booped by that guy capping Alpha

Dammit I need to reload my gun. Nah, BOOP!

I just got a triple boop kill
