Intro Me Gals Part 2

The other day in my sister party :

JT : Thanks for coming.
Guy : Thank you. You r'ber a girl wearing (unsure what he say)?
JT : *Looks at him blank* Sorry bro, seen too many humans so cant click.
Guy : It's ok. But we want to intro you to her. She is single.
JT : Thank you!
Guy : *He was shocked with my answer and he just laugh*

Man everyone is worried man! I don't know why. Really I don't. Can someone explain to me why please???
