You might mistakenly interpret "frowning".

Sometimes our brow shows an expression of disapproval, and yet it is also an image of displeasure. When we are also in our concentration or focusing something we #frown. Besides dazzling sunshine crumpled the middle of my brows.

Why are you paranoid when someone is frowning?

P.S. The word "frown-er", that's Donald Trump. 😄
