Partyboying is when a group of people, or party boys go out, and target individuals from another group, and surround them, 'partying' and act joyfully aimly to scare them off
Partyboying is when a group of people find someone on their own, they go over to them so they are standing right up against the person and start dancing overly enthusiastically. Having pounding dance music is desired but not essential.
The partyboying stops when the victim gets annoyed or after a few moments of dancing after they have joined in.
I was just sitting in the changing room getting changed when all these guys started partyboying me. So annoying.
