yo fr i hate when ppl act like that, like why do they gotta try so hard to be “cool”? it’s not even cool lol. i tried ignoring ppl like that too and they still kept going, so i started just staring at them like dead-eyed, it was kinda awkward but it worked sometimes 🤷♂️. you could also try being sarcastic?? idk depends on ur vibe. just know it’s their problem, not urs. don’t give ‘em the reaction they want!! 💪
