Czech golden shower

When a VZ-61 Skorpion fires a 20-round magazine empties before any of the brass hits the ground.
Defined by Brandon Herrera in his video about the said weapon.

"It's like the Czech Golden Shower. I'm not sure if that's on Urban Dictionary, but I'm sure it's not my description."
