jack my berry - To try and rip someone off like a thief in the night, but it

To try and rip someone off like a thief in the night, but it's all just a silly joke.

Jack my berry, bro, I swear you tried to sell me a fake pizza slice.

You said you'd bring me soup, and I got a cup of lukewarm coffee.

I thought we were best friends, but you tried to scam me out of $20.
