Get the Yampsmug. "Yamp Yamp" is a word originated from Colorado. You are typically suppose to use to the word when one is feeling excited and wants to compensate Yes for "Yamp Yamp". Keep in mind that while saying this word it is used in a shouting motion. If one truly desires he can say Yamp once, but must only be used in a stretched out version "Yaaaaaammmmmpppp" when one is feeling lowkey. It can be used when at a party, at ones crib, or even when one is getting his genitals sucked.
