Someone with BO (body odor) covering it with cologne.
Gross, that person totally smells BOlogne!
The smell you get when a person with bad BO uses cologne. The two smells mix together and you get BOlogne
That fat guy with TTS (TST) has the worst BO. What's worse, he puts on a shitload of cologne so all you smell when you walk in to the room is BOlogne.
