Sarcastic retort used in response to a comment that somebody has used to induce excitement or shock. Used with a sense of
irony, in saying "woop-
de-do", or even "woop-de-freaking-do", the second
party is expressing indifference or mild annoyance at the content of the comment made.
Also used when one has excitedly passed on a piece of relatively unenlightening information.
Analogous with "so what", "oh
wow!", "who cares", "big deal" and "o rly?".
