Who spits on a saddle?

Are you sure it was spit...?

I once saw a lusty homeless man take a good sniff of the lingering lady musk on a cycle saddle, just after after a pretty young thing had jumped off to nip into the shops.

how do you know he was homeless?

It was probably a hipster, and he was just enjoying the odour of Brooks Proofide on a sweet B17.
