To mushroom is to, when singing along to a song, either mumble or sing the wrong words, revealing that you don't really know how the song goes. When someone does this, everyone around them yells "MUSHROOM!" at them, as a way to embarrass them.

When a girl's engorged labia pops out the side of her shorts or panties, it resembles the top of a mushroom.
She was dancing on the stage in her short shorts when her mushroom popped.

An abosolutely wonderful drug that releases your mind from reality. You realize how much life up to 18 is worthless and predetermined, and realize just how messed up and weird the world we live in really is. It isn't a drug to mix with alcohol, heat, or rollar coasters. Unless taken in high doses, it does not make you see gnomes running about in every direction. Only wavy images of things that already exist and an unparalleled body high.
**people who are depressed or have any disorders like being bipolar or anything related should not take the drug. It will cause some the worse times in your life.**
The effects last anywhere from 5 to 8 hours, depending on how much you eat. While having a bad trip, dairy products should be eaten. It helps mellow down the trip. Taking off shoes and socks and being in natural or fimilar areas away from the public also helps relieve bad tensions.
The effects of the drug is determined person-to-person. If you think you will have a bad time.. you will.. if you think you are having a bad time, you are or soon will. if you think everything is wonderful, you will be the happiest person in the world.
1. I cant believe I have to sit in a classroom being brainwashed for 8 hours a day. They tell me what to do, when to do it, and how to do it.

2. "That's wonderful!"

A mind-expanding drug containing psilocybin that makes you see the world in a different, fucked-up way. All your senses are different in a way that you really can't explain and can't imagine unless you try it. In larger doses they can make you hallucinate. Called shrooms for short, and they're legal in Amsterdam.
"Give me two fat tabs and three shrooms, and you won't see me like fat people in steam rooms." -Eminem ("Bad Meets Evil")

"I never meant to give you mushrooms, girl. I never meant to bring you to my world. But now you're sitting in the corner crying, and now it's my fault..." -Eminem ("My Fault")

Michael: "You know what's the bomb diggity...dogg?"
Eric: "Shrooooms man, magic mushrooms. That's what."
Michael: "Actually I was thinking of that new David Hasselhoff song, but now that you mention it, I like mushrooms too."
Eric: "Shroooooooms..."
Michael: "Yeah, me and my homies smoked some good shrooms last night. Usually we just eat coke and shoot up ecstacy. It was pretty cool."
Eric: "What the FUCK? Shut up, bitch. You don't even do drugs. You suck."

Magic Mushrooms, or Shrooms, are a potent drug whose active chemicals are Psilocybin and Psilocin. Sensitive to heat and light. Common effects are dilated pupils, odd expression, and the distinct feeling of super thick chunks of broken light from the milky way intersecting the last thought of every cell in your body as the chair and ground and pizza and table slowly split open and melt.
Fungus Among us. Eat the blue caps and suck the blue stems of these magical mushrooms.
