"So ladies remember! You don't want to be a "Sally Smelly-Crotch" when some guy picks you up over his shoulder."
But SERIOUSLY! If you are in a close personal relationship with this person (and you do have occasional odor issues), the chances are pretty good that they already know you are all stanky down there. Odds are pretty high that they probably don't care either.
HOWEVER. If some random guy is picking you up over his shoulder and carrying you somewhere, your smelly crotch is probably the least of your problems.
In fact, it may actually help you in this situation.
