Salty

According to Arianna Jeret, deputy editor at Your Tango, the term “salty” describes “bitterness or anger tinged with a little extra spice, usually a mocking or self-deprecating note of sourness.” 

Example:

Eli: "Hey Frank, what grade did you get in DeMartini's 302?"

Frank: "I got an A, what about you?

Eli: "I don't care. She only gives out A's to total idiots."

Frank: "Ohhhh someone's salty."
