humger
To describe the mood of one who is angry but also infuses humor into his anger. It is in simple terms, a more elevating and mature form of anger, usually experienced by older, wiser people who are mature enough to not let their anger get out of control and can also mix it with some good humor!
Exactly used like the word "anger" (also "angry") but this one is a humor-anger hybrid to separate it from the more one dimensional and raw anger. Sam's "humger" at the situation reflected an unusual mix of the comical aspects inyertwined with raw anger.
