When you talk up an unattractive person at a bar. Sneak off to the bathroom, bushes, rooftop etc to fool around. Then run off leaving the unattractive person with the tab.

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.
