Planet of Hiruk Pikuk

Once upon a time, there was a planet called Hiruk Pikuk. The planet is full of inhabitants. Many of them live in high density places.

The most common words (as if it was in their own bible) for them:
"F*ck off"
"MYOB"
"Don't touch me"
"Hey, that's mine"
"Don't you dare..."
"Sh*t, I don't have time for this!"

But, the most popular word is, the unspoken word. Gestures of silence.

Now, the planet have forbidden language that it seems like they were awful, those are:
"Thank you"
"After you"
"How do you do?"
"It's a nice day"
"Thanks God I'm alive"

Are you live in there?
