Doing The Astro is defined as whatever you do in secret when no one's around. Everyone does The Astro.
I bet Jimmy's doing The Astro right now. He didn't come to the party.

Kpop group who debuted under fantagio in 2016. The group is formed by 6 members: MJ/Kim Myungjun (oldest member, main vocalist), Jinjin/Park Jinwoo (leader, main Rapper, lead dancer), Cha Eunwoo/Lee Dongmin (vocalist, visual, face of the group, actor), Moonbin (lead vocalist, lead dancer), Rocky/Park Minhyuk (main dancer, lead rapper, vocalist), Yoon Sanha (lead vocalist, maknae). Their fandom is called AROHA.

They are actually really soft and extra, you just have to love them. But watch out when they will come for your wigs with a manly and sexy concept one day.

(also moonbin is maybe secretly a furry and eunwoo is his daddy) ((<- if you seriously think about to stan them don't believe this or wait until you get further into the fandom until you are convinced about this by yourself idk))
"do you know astro? They're so cute uwu."
"yes, but i hope that people will start to appreciate eunwoo for his personality and hard work and not only for his amazing visuals"

A six member Kpop boy group under the company Fantagio. It consists of Kim Myungjun (MJ), Park Jinwoo (JinJin), Lee Dongmin (Cha Eunwoo), Moon Bin (Moonbin), Park Minhyuk (Rocky) and Yoon Sanha (Yoon Sanha).

They’re really extra so don’t be surprised by how mental they are when you decide to stan them.
Do you stan ASTRO? They’re so funny!!

My favourite ASTRO member is Eunwoo because he’s so talented. I wish he was better known for his talent instead of his great looks.
