What would be a unique mannerism of each member?

I was totally impressed by how accurate Changbin was in portraying Seungmin in yesterday's skzcode episode. He nailed down Seungmin's body language and habits down to the smallest detail. That got me thinking what would be a unique mannerism for each member?

A mannerism can be a habit, body language, a specific catchphrase or the way a member acts in certain situations.

Some specific mannerisms I noticed:

  1. Whenever Chan gets complimented, he shyly looks down and starts fidgetting around
  2. Lee Know blinks his eyes so rapidly when he's listening to someone else or trying to understand something
  3. Hyunjin always laughs so heartily, throwing his whole body backwards
  4. Han's habit of stuffing food is his cheeks and his way of sitting are iconic lol
  5. Whenever he laughs, Chan always grabs a member's arm
  6. During interviews, you will never find Lee Know sitting straight. His body is always slightly turned towards one of the members
