When someone that you have been friends with suddenly becomes a chode. Like they just woke up one day and decided to be a giant dick.
"Oh yeah man, he used to be cool in high school but he became an overnight chode."
A guy or girl who was once cool as fuck but seemingly turned into a dick smoke over night. This usually occurs for no reason.
Fuckin James used to the coolest mf ever until last month he became an overnight chode.
