When a fully clothed person goes up to another clothed person on the street and begins to hump them roughly

"Wow man that chic over there is really hot!" , "oh yeah I dare you to go over and street hump her as hard as you can"

22 Hump Street

That one block where all the prostitutes hang out for some reason.

"I saw Johnny heading toward 22 Hump Street"

"That horny bastard"
