A particularly cheap brand of cologne, with a scent that can be described as Eau de Hobo.
Imagine; sometime during high school, 5 teenage boys having a sleepover in a windowless basement. It's summer, it's hot, and there are fans blowing everywhere. I swear this is not pornographic.
Someone is lying on the top bunk, reaches into the ceiling -- apparently, a tile was missing -- and pulls out a clock. Hilarity ensues. He continues to pull stuff out of the ceiling, including a bottle of Brut aftershave, and, finally, a rather well-aged bottle of some cologne called Dagger.
Upon opening the Dagger, we realize that it reeks. Horribly. The stench is some awful combination of cheap alcohol, cigarettes, and B.O. Someone gets the bright idea to assault others with it. Somehow, splashes get thrown into the fans and blown all around the room.
By this time, the host is locked safely in his room, as he has to wake up early for work.
Morning comes -- or, at least, the time of morning when responsible people go to work -- and those of us responsible for the hobo stench are awakened by a shriek.
"Jesus freaking shit, what the fuck is that smell?"
