My friend had the first sip so the pop was hers

first sip grimace

The face you make when you take the first drink of alcohol before a long night of partying. A combination of disgust, low liquor standards, and a lack of self-respect.

But you drink it anyways.

John and I looked at each other, paused, drank, and both made the first sip grimace at the same time.
