Johnny - HELL NO! Never again the last party he had I had horrendous nightmares it was such a major wiener roast.
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.
