How many billiards can you fit in your arse?

Because I want to prank my Tinder date in the middle of sex by crying that I'm about to shit myself, but instead billiards shoot out of me sequentially. Yet my research into the physics and logistics of this makes my idea impractical, and will likely end in my having to explain it to the nurses as they extract the balls out of me.

>also, /adv/ suggested golf balls could work better
