Chronic Yapping Disease (CYD) is a colloquial term used to describe a persistent and incessant tendency in individuals to engage in prolonged and often trivial conversations or discussions. This term is commonly employed in social contexts to characterize individuals who habitually exhibit excessive verbal expression without regard for the relevance or importance of their discourse.

When two people engage in a conversation and begin yapping to the point that a 5 minute conversation becomes a 5 hour conversation (or longer). If another party is involved, the person outside the yap happy pair may end up going unnoticed within the conversation.
Lucia: Hey sorry for not including you in the conversation yesterday, we got a little yap happy. We weren't intentionally trying to ignore you.
Mara: No worries, I know you and Darcy are chronic yappers.

The toll you pay by nodding, mm-hmming, and pretending to follow an endless monologue from a talkative partner so you can withdraw some benefits later. Often paid at dinner, in the car, or while they debrief you on an entire season of a show you’ve never seen.

"Yapping" denotes a high-pitched, incessant, and rapid emission of vocal sounds, often from annoying humans, echoing in an unrelenting, energetic manner, sometimes accompanied by an enthusiastic or impatient undertone.
