"Partir la pana" = To break the corduroy*

To stand out in a positive way. It is also said of the person who is in charge and makes decisions. In this second meaning, the expression reminds us to "cortar/partir la bacalá", as they both mean the same. "Esa canción parte la pana. Será un éxito, ya verás" "Vas partiendo la pana con ese disfraz" "Eres una fiera porque entras partiendo la pana" (From Estopa's song)
