Was having a beer with my music class and when there were just four of use left later, my buddy jokingly hinted for me to make a move on the girl next to me, by putting his arm around my friend next to him, and then the girl picks up on this and says "are you crazy(to my friend)? he's too young, and not my type"

is this a shit test, because i feel like she is into me, but is very defensive and doesn't open up to anyone well(past trauma maybe?)

what's my best course of action if it was a shit test? she's 24 i'm 20
