A phrase used to sarcastically indicate that something which is presumed or
hoped for is, in fact, not true.
Typically used in discussions to either insult someone, or to
refute an assertion by emphasizing why that assertion is
inaccurate.
(As an insult)
*Bill finishes 34th in a marathon*
Dick - Hey Bill, nice job winning first place. Oh, wait.
(As
a rebuttal)
Bill - The United States is in a strong state of
financial security.
Dick - Yes. Good thing our
national debt isn't somewhere around $14 trillion. Oh, wait.
