yapper

Someone who yapps — who talks too much, too long, and often about things that don't require that much talking. A yaper is not necessarily malicious; they're just constitutionally unable to shut up, fueled by enthusiasm, anxiety, or a deep belief that every thought they have is worth sharing in full. The yaper in your friend group is the reason the group chat is always unread. They mean well. They simply have not yet discovered the gift of silence. Often self-identified with a mix of shame and pride.

To talk excessively about nothing important. A "yapper" is someone who won't stop talking; a "yap session" is a long unfocused conversation. "Stop yapping and tell me what you actually want for dinner." The word does the work of "rambling" plus a side-eye.

To talk, especially excessively; to chatter.

Casual talk; chatter.

Describing someone whose entire personality, vibe, or appearance signals that they are absolutely going to talk your ear off. Yap-coded people don't just talk a lot — everything about them radiates future monologues. The expressive hand gestures, the inability to give one-word answers, the way they greet strangers like old friends. Being yap-coded isn't an insult; it's a character read. You know what you're getting into, and honestly you probably knew before they opened their mouth.
