When you stay up for two or 3 or 4+ days in a row. Usually from drug use. to you it just becomes one long day. And it usually requires 24 hours of straight sleep to begin to recover.
Dont bother Bryon now. Gheesh hee's been sleeping for 12 hours now. Yeah he's recovering from the "long day" he'll be sleeping for at least 12 more hours.

More than a day, as in the day before yesterday; such a long day, it was two.
