I know that speedrunners can beat Piggy in a fast period of time, pro glitch speedrunners know all the shortcuts to beat Piggy even faster, developers legit know everything about Piggy, but what is a Pro?

I have referred to myself as a pro in one of my YouTube videos and it has sparked up an interesting conversation in my comment section, what is a Pro?

So in this thread I just want you to answer these three questions,

1. What is a pro?

2. Are you a pro?

3. Are all speedrunners, pros?
