Nerd Is Not An Insult Yall - Tumblr Posts

Why are the people that call other people nerds (or some similar insult) for being smart always the ones who dress exactly the same, thinks getting shitty grades is cool, vapes or smokes, goes to parties every weekend and is an alcoholic since like 13??? Like what do you genuinely achieve from that because you're just proving that they'll have much of a clearer future than you lmao
