This Kinda Happend 2 me once, but i just stoped replying when he started to text me again and ignored her a few days, then texted her back
Me: Cute that your Shopping friend is also inlove with me! You guys have so much in common!
Her: Haha yeah sorry about that! Why Have You Been Ignoring me?

Me: I havnt been ignoring you? I just dont like talking to guys who are flirting with me
Her: blablablablabla
But when I did read what you wrote, I could totally see that happening to me too =/ haha
I would just play along until i get bored then dont message for a few hours
i would text somethink like this after he said "rachels fuck buddy"
HB: i have to apologize for his misbehavior
ME: Tell HIM the apologies accepted
((this is when the guys starts texting me again))
HB: i can see the message...idiot... with love
ME: ok now your just confusin me man first you insult me now you love me? im not into that kind of stuff i mean feel free to live your life like that no problems here im just sayin i like girls
HB: im not gay...? maybe we could just fool around one day and see if we like it though?
HB: (Rachels fuck buddy)
PRookie: O Really :O What day are You free? :O
HB: Wednesday! (or whatever)
PRookie: Deal! but when your done with her tell her to text me back, So cute she finally found some "Guy" to go and shop with

(Then immediately text back and say)
Prookie: Sorry i mean guys! my phone must have a sixth sense or something Have fun =D
And after that just avoid to text her for a few hours then text back
