a swaggerwagon is a type of vehicle that you wouldn't be caught dead in and is so shitty that it just makes it so awesome to where it has intense swag.
friend: dude, why the hell do you drive a mini-van?
person: yo don't be dissin. its not a mini-van. its a swaggerwagon.
A trip to a grocery store, convenience store, or gas station for the sole purpose of buying an excessive amount of junk food and sugary drinks, usually with friends. A chud run often happens late at night and ends with everyone involved hating themselves afterwards.
