Why do boys get triggered when we call them bhai/bhaiya

Like tf are we supposed to call you...like we just met and you are already crying that i called you bhai.. like ofc i will call that because i dont know your name.. or even if we do and you are older ofc we will call bhai why tf is it a problem...literally every guy i know is like "bhai mat bula" TO AUR KYA BULAYU??.. JANEMAN BULAU KYA THUJE PHIR DIL KO THANDAK MILEGI.. CHUP CHAP ACCEPT KARLE NA ABB KYA UNCLE BULAU?? NAHI USME BHI DHIKKAT HAI .. LIKE ITS NOT EVEN A BIG DEAL CALM DOWN
