meaning to walk around aimlessly or without purpose. Used with the verb suru
Due to our company's poor sales and lack of work to do, the vice-president must be bored. Otherwise he wouldn't walk aimlessly around the office building half the day or pace between his office and the newspaper rack talking to himself.
So, whenever one of us salaryman or OL spot him, we begin to whisper amongst ourselves.
XXX san wa mata urouro shiteru yo.
Mr. XXX is walking around with his head up his ass again.
