better a nerd than a boring normie
1- ignore it.
2- don’t be a nerd.
3- if you feel you want to respond to such name calling, just say: yeah whatever bro, it’s a cool game, have a nice day.
If a 13 year old kid says "Bono from U2 plays it" then you are just going to make him seem even less cool.
But the fact is plenty of people play chess, even people the person calling you a nerd would consider cool....
We are all nerds, sure. Being Sheldon is the new sexy.
