a Bruno Day is like a sick day but 100 times worse. It's when you go out one night and get so fucked up that you have to call in to work the next morning and use your personal (sick) time, not because you want to but because you HAVE to. The difference between the two is; a sick day you can at least get up and are still somewhat coherent, with a Bruno Day, you are completely immobilized in bed and spend the next 24 hours cursing Bruno for getting you so messed up.
