Man with Wa Alaykum As-Salam sign on phone

A bald man sits outdoors leaning against a concrete brick wall, staring into his smartphone with a cardboard sign hanging on his chest that reads 'وعليكم السلام' (And upon you be peace). A laughing emoji is stamped to his left alongside the top caption.

Used humorously to describe extreme introversion or antisocial behavior where someone refuses to be interrupted while using their phone.
