Chili nut basket
Pitching chili nuts or peanuts (preferably the former, due to the resemblance to basket balls) into cleavages. The smaller the cleavage, the higher the score, plus extra score for long distance shots. Slam dunks also highly credible, but only for the brave.
Man, I sunk a nut in an A-cup when chili nut basketing at the party last night!
