Your Sisters Ass 

A hard seventeen hand in a game of black jack. You want to hit it but you cant. also known as the mother in law hand

The dealer was showing a ten, and as usual the cards werent going my way. I was dealt an ace and a six, which made my hand a 7 or a 17, so I went by the rule always hit a soft 17 and I drew a 10, which put me right back at seventeen, which is just as helpful as your sisters ass, you want to hit it but you cant.
