It can be both, but I’ve definitely been punched in the face by pure cologne/perfume on multiple occasions. Probably even more often than I’ve ever smelled BO equally as bad, including my own on those lazy stay at home days.

Though I do try my best to not get within smelling range of others regardless, so maybe cologne just has a larger radius most of the time. I’m definitely not sniffing pits to see how their BO mixes with what ever extra rank they’ve added…
