first impressions and flirting???

Je
So my friends set me up with this guy who Apprently is perfect for me. And we're going laser tagging as a group for my birthday next week.
The only problem is, idk how on earth to make a good impression! I'm such an awkward person 😰😁 let alone how to flirt... I've never had any experience. I've never known of a guy that I actually like enough to care about saying something like 'oh urm hey,' *avoid eye contact*and make up some absurd lie to get there attention. (I accused one guy of hacking into my school log in... Idk either) 
I'm so nervous, idk what to wear or what makeup I should do or how to talk Orr anything!!! I'm so anxious about the whole meeting thing.
Please help!!!!!
