barbilla
/baɾˈbiʝa/ · B2 · noun · f
chin
🧔 barbilla = barba (beard) + -illa (little): the little beard spot
Spanish barba means beard, and the diminutive -illa means little. So barbilla is the little beard area, the chin. The bird wattle hangs from the same spot. The pull-up sense comes from raising your chin over the bar.
