A form of baiting that substitutes engagement with pathologization. Instead of addressing arguments, the Grassbaiter diagnoses the speaker: "touch grass," "take your meds," "you need therapy," "go outside." The term derives from the classic "touch grass" insult—meaning you're so online you've lost touch with reality—but extends to any attempt to frame the other person as mentally unwell, socially maladjusted, or psychologically broken. Grassbait isn't about exchanging ideas; it's about disqualifying the person having them. The goal is to make the target defensive, to cast doubt on their sanity, and to position the baiter as the healthy, normal one. It's disagreement by diagnosis, argument by armchair psychiatry.
