Reverse Cologne and Perfume
The scent gradually lessens and fades the Closer you get to someone. This is to not intentionally address themselves with a scent first. Spray it on and you smell good. When a person is gradually attracted by the scent, they assume it was you in whom they were interested and not your cologne or perfume.
The smell is based on your natural body odor masking the airy and floating cologne and perfume. The closer they get to you, the more you smell like yourself until your own smell takes over.
Reward: To smell like Mel Gibson's body odor!
