My friend most likely says sarcasm if I do something too neat (for teens like me, I'm 16 years old), especially on computer-related things. When I open many tabs, he might say "all you open," signs he wants me end my opening many tabs habit.

Another friend, asking for my argumentation. But she makes a noise signs if I should stop saying any words.

And, a group of friends, including who very like to say sarcasm to me. Most likely, they make bait every time to bully me. Sometimes, they uses middle finger as dummy of my interest or my missing belonging. They sometimes show their middle finger when they do something that seemed to be want to show something match to my interest or my missing belonging, but not.
