"So... I ran out of things to say, I'm just gonna pull out my phone, is that okay with you?"

"You're not even gonna try to restart the conversation???" mock indignation

"Do you know why I'm standing EXACTLY this distance away from you? Scientists say it's the optimal distance to reduce awkwardness..."

Whenever a girl does something like not sit by you on a couch or heck if you don't sit by her because your nerves got better of you

"It's probably for the best we sat apart, we're still at that awkward stage of meeting a new person aren't we?"

conversation stalls, pull out my phone "Soooo... did you know it's currently 63 degrees outside?"

....

"Great, now we're talking about the weather"

Once I realized that I can go all meta in social situations and point out awkwardness or just point out the underlying mechanisms it became really fun. Note that I only do this when I'm 1 on 1 with another person, it can actually get weird if you do this in groups. This kind of banter fits my personality really well and I just genuinely have a shit ton of fun doing it. Of course I only use these lines when the conversation starts to die or I notice the subtle tension of awkwardness when our bodies are too far apart (like she sat away from me or something). I made this post in the spirit of not giving a fuck.
