Oakland clamshell
An Oakland clamshell is when you use a bulldozer, a big black dildo, and your fat black neighbor to ram her butt and shake her until she explodes.
My cousin did the Oakland clamshell with a bulldozer and her aunt. It was a mess.
At the block party, DJ Dildozer came through and shook the whole neighborhood.
My mom tried to do the Oakland clamshell, but the dildo broke and she got stuck.
