“T’morning; that time in which the “night” morphs into the “morning” but you don’t want to call it today as you have yet to go to sleep from yesternight. Used mostly as a farewell or a greeting.
Joe: I should really get going, it’s so late. Goodnight.. er.. Good morning? You know what? T’morning to you!
Sam: T’morning!
Sam: T’morning!
