"Who's this?" is a phrase you text to sketchy numbers that text you first claiming that they know you.

It may be the cause of a blackout the night before, or sketchy kids asking where the bud at.

The act of sending a, "Who's this?" seems harmless but the act of receiving it feels like a minor diss.
"yoooo, do you know who has weeeeeed?"
"...Who's this?"

"hey, nice meeting you last night, i had a good time ;)"
"Who's this?..."
