Inside-Out

When someone has been on the toilet for so long that they've almost flipped "Inside-Out" due to how much pushing out of poop they must have done.

David: You were in the toilet for a long time!
Bob: So sorry, I think I ate something bad earlier.
David: We all though that you had flipped inside-out by now!

Insider Sipping

Freelancing in a coffee shop and stealing two sips of coffee from each cup. Like Insider trading, it's "insider sipping" :D

I am ultra broke and can't afford a coffee. So, I started working in a coffee shop as barista for insider sipping!
