@skematica I just looked. It’s in the dictionary:
pootle ˈpu:t(ə)l ♫ verb intrans. colloq. l20.
Move or travel (along, around, etc.) in a leisurely manner.
B. Bryson With two hours to kill, I pootled about aimlessly. M. Sawyer Pootling along at 20 m.p.h. in fourth gear.
ORIGIN: Blend of poodle verb and tootle verb.
