Frierendes Gesicht

An icy-blue face with gritted teeth usually depicted with icicles clinging to its cheeks or jaw, as if frozen from extreme cold. May also represent unfriendliness (slang, cold) or excellence (slang, cool or chill).

Apple’s design features the same expression as its 😬 Grimacing Face. Huawei's design has a chipped 🦷 Tooth.
