mushroom clouding 

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.

Mushroom Burn 

When one drunk dude passes out at high noon with his cock on a girls cheek in the middle of the afternoon allowing for the sun to burn them. Once sobering up, the woman realizes that she has a mushroom burn on her cheek when looking at a reflection in a mirror.

Tom: Bro, did aunt Sally have a mushroom burn at the family gathering this evening??
Bill: She definitely did, but so did her daughter...

Tom: They got a new pool cleaner, didn't they?
Bill: Yes, yes they did.
