Bowsie-Wowsies

(noun; also exclamation) The tingly, vinegar-like sensation that occurs in the upper spine and back and when a person is excited or nervous, or when he or she is experiencing a sense of great anticipation. It is best applied in generally positive situations.

In such times, the words "Bowsie-Wowsie!" can be shouted extremely loudly, which serves both to indicate the shouter's current state and to relieve the body of tension.
