Someone who plays Skyrim all hours of the night, has 50+ hours logged on the game and is addicted. This person is constantly playing Skyrim. This person no longer contributes to the economy because they spend all their time at home. Also this individual has no social life, because they end up neglecting their girlfriend and their friends. The only way a Skyrimer socializes is through chatting online with their friends while playing Skyrim.
A Skyrimer is a individual who stays up until two or three in the morning, sometimes pulling all nighters playing Skyrim.
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.
