*my 8th grade class*
person 1 "wait there are different flavors???"
person 2 "so does that mean we can collect them all and taste the rainbow?"
person 3 "i'm going to try that..."
When 1 person from each race is standing/sitting/hanging out in the same room.
Today I was able to taste the rainbow in my ap stats class.
When you climaxing and your cum is the consistency of the original skittles.
