Granted I don't think I can assign a specific group to this habit, I do think a very high concentration of them tend to congregate in gym locker rooms: "Oh I just finished working out and took a shower but I think I still might reek of gymfunk so I'm going to whip out my bottle of cologne and spray my neck, back, arms, stomach, crotch, legs, shirt, underwear and pants 37 times regardless of how many others around me can now taste it and are having convulsions from it."
