Where you feel shit the next day as a result of tiring yourself out the previous day. The equivalent of a normal hangover but without the alcohol.
Kevin had one bitch of a tiredness hangover today after fucking that new girl of his for 10 hours straight yesterday. He's gonna need a lot of caffeine and sugar to pick him up.
