What does 69 mean??

i have seen it tattooed on peoples back, and saying "lush 69"What does 69 mean??
the 69 is a sexual position in which both partners perform oral sex on each other at the same time in a position similar to the number 69
it's a sex position and it's also a symbol for cancer star sign.
68 is actually the fastest speed of sex, because at 69 you have to turn around.
I believe it is a zodiac, the one for cancer...... and It's a sexual position.... Most tattoos I have seen of this symbol were the cancer tattoo.... now the lush part, well maybe that person likes to get drunk before they 69.........
Lush 69 means lets sex now
