Why do my crush's friends tap him on the shoulder whenever I'm around him?

Prolly likes to joke around.

Or what you're probably wanting to think is I'd that he's flirting with you, which could also be the case.

my first thought is they have an inside joke about you or it’s like they know he likes you romantically so they’re teasing him about that

He is letting him know that you are near.
