When someone says that they aren't gay, but could possibly be a little curious, they are only made of 25% fruit juice. When someone is fully gay, they are 100% fruit juice. Typically, the average person is between 1% and 5% fruit juice. The term fruit juice is related to the percentage of homosexual you feel you are, compared to the total amount of gender you are. So, let's say you are 70% straight, and 100% male. The difference between your percentage of straight and percentage of gender is the amount of fruit juice you are. Therefore you would be 30% fruit juice.
"Yo man are you gay?!"
"Nah, I'm only 25% fruit juice."
