RPB 

Rocket propelled butt plug, similar to a rocket propelled grenade (rpg). However it shoots a large butt plug, comparable to Bullet Bill from Mario.

A man running away from the army, was shot by a newly mechanized butt plug launcher. The RPB quickly took down the man leaving him with a forever prolapsed asshole once they took it out

You spelled ROBLOX wrong.

Instead of typing RPBLOX instead search for ROBLOX
