night owl guilt 

The feeling you get when you stay up until all hours of the night, whether for work or play, then other people rub it in your face that they got up earlier than you.

"Yeah, I slept until 2pm, I was so tired from being up so late."
"I got up at 5am to go for a run before work"
"Shut up, you're giving me night owl guilt."
