verb/ˌno deˌxaɾ ˌtiteɾe kon kaˈbeθa/
to smash up everything in sight; to do away with everything
Literally, “to not leave a puppet with a head”. The term alludes to a scene in Don Quixote (Volume 2 Chapter 26) in which in one of Don Quixote's daydreams he mistakes dolls for a maiden's real captors and thus cuts off all their heads.
