(•́⍛•̀; ≡ •́⍛•̀;)ｵﾛｵﾛ

The sign in the middle, ≡, is called IDENTICAL TO in Unicode, and for once the label fits: the face on its left, •́⍛•̀;, and the face on its right are written with exactly the same characters in the same order. Those three stacked bars also look like the speed lines a comic artist draws next to something in motion, so the pair reads as one face darting back and forth, caught in two places at once. In each copy the mouth is ⍛, a symbol made for the programming language APL; its full name, APL FUNCTIONAL SYMBOL JOT UNDERBAR, describes it well: a small ring (the jot) with a short bar underneath. The eyes are bullets, •, four in all, and each comes with a combining accent: in both faces the left eye takes an acute and the right eye a grave, though some fonts don't set those marks over the dots and let them slide right, toward the ⍛ and the ;. The ; that follows each right eye is a bead of sweat, two in all. Japanese has a word for exactly this kind of panicky back-and-forth, oro oro, used for someone flapping around without a clue what to do, and the face spells it out for you: the four half-width katakana ｵﾛｵﾛ tacked onto the end. On X it closed a post lamenting four bottles of face mist used up in a single summer.
