Verb: the act of looking busy, while really just mentally spacing out in order to avoid helping with housework. To wander around aimlessly instead of getting dressed and ready to go, often done unintentionally when hungover.
Leenie, what are you doing in there? Can you please stop buckfarting around and get dressed before we're late for dinner.
Ryan Thomas! Stop buckfarting around and get your ass in here and help me with these dishes!
