Mushroomhead 

I am adressing the conflict between mushroomhead and slipknot. first of all about the mask issue NEITHER BAND COPIED THE OTHER!!!!! THEY EACH CAME UP WITH THE IDEA ON THEIR OWN!!!! Both bands are so different you can't really compare them slipknot has taken a more hardcore and aggressive approach where they are always serious in their songs. mushroomhead has a slower more gothic feel and ironically do incorporate some humor into their image. The fact is that if you like mushroomhead there is a 90% chance you are from Cleveland because they are less popular than slipknot. If you like slipknot you are looking for more thrash like stuff.

Guy 1:did you hear slipknot copied mushroomhead.
Guy 2: (bitch slaps him) what the fuck is wrong with you slipknot had never heard of mushroomhead when they chose the mask idea.

Mushroom Top 

A term to descibe the image of a woman's flabby calves spilling over the top of a pair of boots. Similar to the term muffin top, except on one's legs.

Did you see her mushroom tops? Her legs barely fit in those boots. Her calves were pouring out the top.
