I'd be the first to start this. Other people in this case can be anyone, at work, on the street, in the shopping malls, etc.

Today I went out in the afternoon and, surprisingly, smelled:

2 people wearing Dior Homme (a bit unusual here as it's not so popular)
1 Acqua di Gio
1 Bvlgari au the vert (could it be Elizabeth Arden Green Tea?)
2 Cool Water
1 L'Instant

What's yours?
