fucktaki mushroom 

When some accidently use the word "shit" when they wish not to, they might add "taki mushroom" so it is as if they were not swearing at all. This method may also be used for the word "fuck".

One day I accidentally started to say "what the fuck" in maff class when informed of a homework assignment. I knew this would not fly. Thinking quickly I added "taki mushroom" to the end. The day was saved. No one suspects me of being a potty mouff. The teacher, coincidentally, is actually quite fond of fucktaki mushrooms in her spring rolls. Oh fucktaki mushroom! I misspelled "mouth".

Unlike what most think, it is more than a simple pizza joint down the road. It is the term used to describe being high to the point of absolute peace in the mind. You achieve the highest state of mellow. It is named this because the drug often used to achieve this state of mellow is the shroom.

Bob Marley founded and represented the Mellow Mushroom society!
