When a person/s has a larger assular device, more sweat is held in one area. When the fart goes through the assular device, sweat particles are picked up, creating more assular stench.
When in World of Warcraft a stupidpaladin throws up his Divine Shield to block out all physical and magical damage and hearthstones away.
The Paladin is riding his mount through Searing Gorge. He comes across a horde. He unmounts and starts to fight. He is getting his ass kicked so he "bubbles" and uses his hearthstone to get away.
