Meaning
A face with eyes squeezed shut and a tight, wobbly mouth, as if pushing through pain or effort. Literally it shows perseverance.
It fits gritting your teeth through a tough workout, a headache, a long queue or a task you just have to finish. It often reads as struggling but not giving up. Pair with 💪 for determination. Example: “Last kilometre of the run, legs on fire 😣💪”.
