mushroom funk 

Male ejaculate. Due to the strong resemblance between the penis and a mushroom and because some people believe male ejaculate smells like mushrooms.

"Wow! She really digs the mushroom funk!"

"After she went down on me she had some mushroom funk in her hair."

Mushroomed up 

To get all high and mighty on mushrooms. This is a state of being evinced by happiness, hallucinations, mightyness, and the epitome of awesome. This isn't a state to be undervalued. Envy those mushroomed up.

Dude: I'm going to get all mushroomed up and find god.
Other dude: That, good sir, is an aspiration of manly proportion.
Dude: That's the only way I do.

Mushroom Forest 

Any online space that is full of dic pics. Often these are posted without prompting by guys seeking validation that they don't have a teeny weenie or are trolling the waters for a quick slam.

Alternatively, a space full of dildos.

Let's go to /soc/ and get lost in the Mushroom Forest.

Don't go in Jennie's room: it's a Mushroom Forest.

An innocent person caught in a crossfire

In some cities, Dr. Sherman learned that drug gangs actually have a name for innocent bystanders who are caught in cross-fire. They're called mushrooms, because they can pop up anywhere.
