It is more used to "jump to the jugular". It means attacking with everything, decisively and with the intention of ending the contest immediately. It is a simile, used in Colombia, to indicate that it will try not to give the opponent a chance to defend themselves or that their defense is ineffective. Accuse with sufficient and forceful arguments. Overcome in a short time (it is assumed, that in the jungle, the fiercest animals attack their victims by the neck, in order to tear the jugular : the victim dies in a short time).
