funnel tunnel 

When you insert a funnel into your woman's ass and then proceed to pour different colored marbles into it. You then perform anal sex on your lady to mix them up. You and your buddies can then place bets on which color she'll squeeze out first.

Damn homey, I lost 50 bucks playing funnel tunnel with that new chick. I should have picked blue!
