The action of folding ones hands together and then fisting a vagina or anus at a high rate of speed. Typically crisco is applied to the forearms and fists. If you are a jilted lover perhaps you will give your partner an ungreased super double fister.
Dude, the other night Stevie D and his new girlfriend gave each other super double fisters - I heard the girlfriend gave stevie an ungreased super double fister. Man, his anus must lbe the size of a peanut butter jar.
