To PTB, is to "Pass the Buck". In other words, it's to delegate a task to another employee or department, when the said task has already been delegated to you, by another employee or department. It is meant to be used on a particular person when they are found to re-delegate tasks frequently.
Darren asked Dan to call everyone in the office to find out who was attending the lunch bbq, Dan PTB'd to Shaun, and Shaun had to call everyone.

When Bill delegated a task to his own supervisor, he was crowned the PTB king.

Pat the Bun. A way to say LOL, but when you really mean you are laughing out loud and not just using it as a filler as lol has come to be used as. When something is so funny you have you pat the bun from uncontrollable laughter.

example 2:

"gay guy - …then we got to my house, he took his clothes off so fast and his ripped-ass body was, like, yummy, …
straight guy - … //panicks// Oooookkkkkaaaaayyy…
gay guy - then we sprinted to my roommate's bedroom, I knelt down…
straight guy - Okay just PTB, man! PPPPPPPTB right now!"

example 3:
"- I am moving to Mexico in a month!
