expressionspejorative-languagesingle-word-requeststerminology

With tensed muscles and looking "difficult" (as I don't know how to describe this any better…) Not done most excessively (a face frown as much as possible), but kind of like someone who (pretended or not) is having a hard time. You may have seen this kind of face before from young people who take a lot of "selfies".

Best Answer

I would say the person has a dour expression or is stern or is gloomy.
