stoners rainbow 

When corner hitting, The corner that the weed is being hit the most is the most burned. The weed changes color according to how much it is burned.

From the corner being hit it goes as follows.
White
Gray
Black
yellowish green (the part that is barely touched by fire)
Lastly green (weed that has not been burnt yet.

I made a perfect stoners rainbow last time I smoked. The colors were all there. It was beautiful.

taste the rainbow, BITCH 

Similar to the sexual term, it generally means to have somebody in a favorable position, like after beating the shit out of them, and ramming any object of your choice into one of their main orifices, like their mouth or anus.

However, many people don't know how to taste with their anus, so you might as well just say it in a foreign language, like:

smak tęczy, BITCH
OR
die smaak van die reënboog, BITCH

Mr. Maynard hid in the bathroom stall, waiting for Mr. Concubine, where he proceeded to rip his genitalia off and beat him with it. He then whipped out his OWN dinosaur penis with flaming coconuts and forcefully rammed it into Concubine's orifice while saying "TASTE THE RAINBOW, BITCH!!!!"

Triple Rainbow 

A triple rainbow is where you purchase a carrot, a cucumber and a banana simultaneously, then later insert them into every crevasse of your body possible, creating the "Triple Rainbow".

John, you'll never guess what I can do! Oh God, please tell me it's the Triple Rainbow...
