DEAN: Hey Lane. Are you going to this big shindig at the inn tonight?
LANE: Yeah, I’m just trying to trick my mom into not going with me.
A shindig is an informal word for a small party, especially one that is lively, noisy, or out of control. Originally it was entirely rural, and seems to come from the American South, with the suggestion that the dancing was going to get so vigorous in such a small space that you’d literally be kicking people’s shins. It is not impossible that there is a connection with the Scottish Gaelic word sinteag, meaning “jump, leap”.
