A new phrase girls use ever since Facebook came out,

Whenever a guy pokes the girl or says hello the girl will think she is smart by using the modern phrase who is this? But in reality she just makes herself look stupid

Most the time the term is used when the girl obviously

A. Knows that she does NOT know the guy, but want to be a smart alec to make the guy feel bad and for her to feel good about herself

Or

B. She knows the guy but she wants to pretend like she never seen the guy before to cover up something

Most guys would go cry to their mommies when a girl says " who is this? "

But a few of the stronger ones with more pride and dignity will just think the girl has a peanut for a membrane
Guy: Hi its Jake

Girl: Who is this? ( thinking she is getting the best of this guy by pretending she does not know him, stroking her own ego )

Guy: This is the second time I introduced myself to you, and you still don't know who this is, you must be retarded or something, we'd probably not be a good match anyway
