What 眥 means
It names the corner or rim of the eye. An early Chinese dictionary, 說文解字, from the Han era, explains 眥 as the eye rim. The character combines 目, which supplies the eye meaning, with 此, which supplies its sound.
Chinese compounds can turn the anatomical image into a glare or resentment. Japanese dictionaries record まなじり and めじり for the eye corner, and にらむ for a glare.
Someone sent me 眥—what does it mean?
Usually, it is a literary word, not a mood signal. Alone, it names the eye corner; in a quotation, check the full phrase. 睚眥必報 describes avenging even a slight, while 目眥盡裂 pictures eyes seeming to split open with fury.
Standalone 眥 is rare and bookish, more at home in Chinese or Japanese reading than casual messages.
Do not infer anger from 眥 alone; that force comes from particular compounds.

1Why does 眥 show as a box on some devices?
Because that device's fonts have no glyph for it. The character is still correct and still copies correctly — the box is a missing glyph, not a broken character.
