I remember the saying "if it smells like cologne, leave it alone ... if it smells like fish, it's a tasty dish"
Don't get me wrong - I would prefer a tootie that has been cleaned and purged, but the alleged meaning of that phrase came to mind after reading
Some Chick On Yahoo! Answers said:
Cologne means that she is trying to camouflage the bad smell.
Fish or onion is normal.
Have of it freely.
