It's a Canadian film thats basically about a hobo who fights crime, battles corrupt cops, killing pimps and pedophiles, all with his shotgun. I really recommend that you buy this movie on iTunes, or wherever you can get it at.
Yo dude let's go watch Hobo with a shotgun! What's it about?? A hobo with a shotgun.
If someone has beaten you in saying "Shotgun" for the drivers seat, you can say this, meaning that you can sit on the shotgun's lap.(unless the person likes to have other people sit on their lap((Freak!)) then thy should get up)
