google refund 

a feeling of dismay upon finding one's supposed neologism on a google search.

refund gap 

The excessively wide space between a woman's breasts, indicating a poorly executed breast enlargement procedure. Ideal breast cleavage is minimal, so any woman showing off a pair of huge, spherical, gravity-defying boobs that have an inch or more of space between them arguably deserves a refund from her plastic surgeon.

That cougar was totally hitting on me, but I was too weirded out by her refund gap to take her seriously.
