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.."

Get the Jamacian Bobsled mug.
The act of putting toilet paper in the water before taking a dump, so there won't be skid marks after flushing.
If you don't want them to know you dumped in there, just do a Jamacian Bobsled and light a match.
