brown mushroom 

After a prolonged bout of anal sex, the giving party turns the recieving party around and proceeds to thwack them on the forehead with their penis/dildo leaving a brown mushroom in its stead. Also known as the brown mushroom to go, because one does not want to stick around after giving a brown mushroom.
notes: brown mushroom is only theoretical, poo does not actually stick to the penis in quantities that would make this act possible.

Johnny gave Jenny a brown mushrrom...to go.

Mushroom top 

Male masturnation technique wherein the man vigorously oscillates the palm of his hand solely on the tip of the penis. A pleasureful experience if done masterfully, and vice versa

Ed realized the tip of his dick is pretty sensitive, so he decided to polish the bishop mushroom top style this afternoon.

Mushroom Method 

1. A public relations strategy frequently used by government agencies, corporations and law enforcement officials. It means "feed them manure and keep them in the dark."

The goal is to delay any public disclosure of information as long as possible by releasing half-truths, distortions and useless information to the media.

Origin of the Metaphor: Farmers use manure, millet and recycled wood chips to grow mushrooms in dark, steamy rooms. Hence, "feed them manure and keep them in the dark."

Detective: "That reporter from the News-Tribune keeps calling me about our runaway child case. What should I do?"

Police Chief: "Try the Mushroom Method. He'll lose interest after a few days and move on to something else. I've seen it work a million times."

infected mushroom 

The best psy trance artists ever.

Erez and Amit Duvdevany from Israel have sold more than 250,000 albums world-wide and more than one million people have flocked to see them live. Brothers who were classically trained, hated it, but now extremely grateful towards their mother because their classical music skills greatly contributes to writing their own music.

Infected Mushroom playing live is simply astonishing. They actually PLAY LIVE, with synthesizers, electric guitars that are crazily tuned, and singing. In Israel and Brazil they are treated as proper rock stars.

Even though psy trance is much deeper underground than trance, Infected Mushroom has sustained places in the top 50 DJ Mag polls. Their albums include Israliens and one of their best tracks is Arabian Nights on Mescaline.

OMGuh just listen to IM's tracks! You'd have to be on magic mushrooms to make this kind of music!

Infected Mushroom's coming to Peru? Let's go and get infected!
