A daytime rager, typically performed alone and precipitated by a day off or a stroke of good or bad luck. Usually followed by a dayover and feelings of intense shame and loneliness.
Jim got fired this morning, so he came home and had a dayger. I would have gone to support him, but I still have a job.

A day rager, typically celebrating some sort of event, holiday, or sometimes for no apparent reason. Activities include a heavy amount of music, bbq-ing, beer pong and drunk bitches.
Rob is throwing a huge dayger since we don't have school on presidents day!
