Any morning when one finds themselves coming down from a trip.

This definition comes from the phrase coined by Hunter S Thompson, "Every day is Saturday Night, Every morning, Sunday Morning".

This phrase also appears on the Ladytron song "the Weekend" and is referenced in several other songs by the same band.

Get the As Sure As Sunday Morning mug.
A swollen, chaffed or sore asshole that can only be achieved after a solid ass-pounding friday and saturday night. Most common in insecure drunk women, dope fiends, inmates and Justin Beiber fans.
