You wave with both hands
You unconsciously do aegyo
You randomly break into dance
You laugh with your whole body and clap
You show your love with your arms/hands
You know you are a Kpopper on Tumblr when you start mimicking the GIFs in real life:
So…
“You laugh with your whole body and clap”
OMG. yes. I do this. And people find it weird already. aigoo~ I sometimes end up rolling on the floor. XD
