Jamacian Bobsled 

An sexual act in which you find yourself at the top of a staircase engaging in doggy style. The female must be on her hands and knees. When you see that she is near her climax, knock the arms out from beneath her and ride down the stairs. If you feel the need you may scream "Ya Mon!" when you yourself reach climax. Works best with red stripe beer.

"My girl has been afraid of the staircase ever since that night I pulled out the Jamacian Bobsled on her.."
