going on a roadtrip when you're broke as. Driving cross-country, sleeping in your car, and basically not spending more than you have to, and NEVER in good hotels. Congratulations, you have become a temporary hobo, traveling the world.
'Dan drove on a hobofest down to see Meghan in Florida last week.'
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.
