Mine is - Algorithm. Ever since people have learned some of the inner workings of how content is suggested to them, that became the new spammed word that easily got exhausted within the week of it being used.
Yeah, an algorithm does indeed pitch you things of what to watch or listen to. But there’s more going on than that, but people all the time just stop at that word and expect everyone to suddenly understand it. Sadly, most people just buy it at face value.
This one amuses me. It looks all fancy in writing. But if someone says “milk toast” and you don’t know what it means, they just sound like an idiot.
