Random words/letters under peoples names…

Hi,

ive noticed recently random words or letters under peoples names. There seems no patterns to who it shows on or why the words or random letters in particular are shown….does anyone know what it/they mean? Cant find anything online or on facebooks help and with no way of asking facebook direct thought id try here….????????‍♂️

Examples are ‘photo’ under one and ‘ate’ under another and have seen ‘Te’ on another….random!!
