facety
Playfully rude; feisty.
My teachers, in the main, thought this was good, but in my parents' opinion I was just simply “facety,” or in plain English, rude or impertinent. Well, the discovery came about as a result of my being “facety” to Mavis.
Where it comes from
Apparently an alteration of facey (although it is attested slightly later) with epenthetic t; perhaps compare -ety, feisty, or Sranan Tongo fiésti (“dirty, nasty”) (19th century).
