Puking Mushroom 

The Puking Mushroom is when you are having sex with your girlfriend doggy style without a condom and you don't want to cum inside her, so you take out your dick and pop the head in her ass and cum.

I was having sex with my girlfriend last night doggy style without a condom and I didn't want to blow my load, so I gave her the Puking Mushroom and she loved it!
