Oppositely charged banter. As opposed to banter, this often occurs in the form of a statement or comment which incites no laughter or positive emotional response from the recipient audience, though it may in rare cases provoke the audience to hit, swear at, or look pitifully upon the one who discharges the antibanter. Nobody is immune to antibanter comments, but women are more prone than men.
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.
