1. A term used in reference to a person who simply doesn't stop pontificating/talking. Usually the 'superpower' during a conversation. Someone who never runs out of material regardless of life situations for they do not stop talking! 2. A yappy little dog that resembles the features described in definition 1. Normally in the Terrier class of canine, but can just be a dog that, not unlike a human 'Buck Buck Buck', seemingly will not cease barking. 3. A political 'talking head' that promises things to no end in sight, however, more often than not, results in very little positive outcomes, though not always!

A neighbor: "That little white Westie terrier is cute as hell, but man, what a 'Buck Buck Buck'! Won't stop yapping until either the owner shuts him up or if someone jokes about getting him fixed! Cares about his 'arf balls' too much!!
