Everytime I get a new haircut with skin fade, people come and keep slapping my head. I understand it's a joke and I can tolerate it, but sometimes people do too much and I don't want to be aggressive back so it doesn't seem like I'm annoyed or so it doesn't become physical because I'm quite a physical person. On Friday, I and a haircut and lots of people came behind me and started slapping my head - and the slaps do hurt a lot. Some people actually slap my head soft, but when people slap it a lot and it hurts, that what I don't like. I don't know and effective way on how to stand my ground and this as I don't want to seem annoyed or escalate it into a physical fight.
Dude standup for yourself. If it's close friends then tell them in a friendly jokingly way that its annoying. If they aren't friends don't let them touch you like that
