Cleveland Steamers and Hot Karls

I would normally never bring up this kind of thing but the other night we were watching Seth Macfarlane's Family Guy and we heard an expression we'd never heard before.

Peter was working as a prostitute on a street corner for some reason when his wife, Lois, pulled up. He offered her something called a Cleveland Steamer. A what? From Cleveland?

I had no clue so I had to wiki it. Here's the write up.

During the search, we also came across something called a Hot Karl.

Life's weird.
