Basically anything that 4chan starts using and then is picked up and butchered by fucking everyone. "Seethe, malding, cope, etc." and next thing you know those words nearly lose all impact or meaning and makes the people using them look incapable of coming up with an actual retort. Those words can be put to humorously valuable use in the context of a meme (which takes effort, a turnoff for the kind of people I'm referring to), but when it gets to the point where people voice an opinion backed up with facts and they're met with "jesus, what a cope" then it's a little ridiculous.
Certainly they got more than this, like a counterargument, right? All too often the answer is either "cry more" or simply no response. If you want to disagree but don't have anything to add, then simply disagree.
