Alpha Douche Cockblock- How to Deal

I walk to the roof real quick and see a bunch of people huddled around  a space heater, so I walk up and with 4 words, bust open the entire set, "It's a DC bonfire"- Boom- every girl is crackin up and the alpha douche of the group is already pissed at me haha- it really doesn't take much

I situate myself in between douche and the girl I was most attracted to, and I'm just being friendly- I haven't even communicated interest yet, which was key, because douche plays his cards WAY too early... see, before I conveyed any interest whatsoever, he immediately blurts out, "She has a boyfriend, don't even try"- played his cards wayyy too eaerly for dealin with a guy like me.  It doesn't effect my emotional state in the slightest. I remain completely calm and relaxed, maybe even just slightly amused. 

"That's cool,"

and then I promptly ignore the dude, turn to the girl, laugh and just am like, "I can't believe he would say that- he TOTALLY called you out"... she starts to laugh and is like, " I know, he called me out".....and then she asks my name and I ignore the question, and keep basically just talking and being funny and ripping on the dude, in a VERY lighthearted way, for the whole "bf" thing.... and she keeps asking my name, and the thid time she asks she starts escalating on me, and I grab her hand and hold it for a moment and we make eye contact and I just say, "Don't even think about it bad girl" and she starts giggling SUPER hard, and I let go of her hand and introduce her to my wing.... but before sealing the deal and turning my back to the dude, and thus completely blocking him from the conversation- I grab the hand of the other girl from his group, look at her, and am just like, "Comne hang out with the cool kids" and give her just super super strong eye contact and she is like, "ooo is THAT what's happening over  here" and gives a super super flirtatious smile- also it should be noted that my wing was now talking with the other girl to keep her occupied. 

Also- you may be asking yourself what was the douche doing this entire time? He literally was doing nothing.... he fired all his bullets and when he saw that none of them hit me, and infact I was now using those very bullets to shoot himn down- the kid just shut down completely... and once the girls were chiln with us he COMPLETELY shut down and left (my wing got in a fight with him later over these girls- turns out he's buddues with the one girls bf)

So the other girl comes to the other side and I seal the gap by turning my back to the dude. So now it's him and his 2 buddies and no girls lol.
