When you fart under a blanket and then pull the blanket down, releasing the noxious fumes into the general area.

The benefit of mushroom clouding is that because of the blanket, the fart is frequently muffled or even goes unheard
My wife and I were watching TV in bed when she grabbed the remote and changed the channel. So I let one rip under the blanket, mushroom clouding her as retribution.
