TransFormers which have a Nebulan (humanoid) companion who transforms into the head of the transforming robot, and does not form part of (but can usually drive or otherwise connect to) the large robot's vehicle and/or beast mode/s.

Sometimes used to mean the large robot, sometimes the small figure/head. (Japan only: some heads were brought out without bodies, and all heads were interchangeable between robots, making more sense of the term "headmaster").

Of course, it also means a male head-teacher (now rarely used for PC reasons) - presumably it's a play on words (used as a model for later names such as Powermaster, Targetmaster etc.). Initially appeared in series 4 of generation 1.

Also, the first series of the Japanese Transformers cartoon (the 4th series overall) is called "TransFormers Headmasters".
The Headmaster Mindwipe, a Decepticon who turns into a bat, has a Nebulan companion, Vorath.

The act of soliciting for the purposes of prostitution, i.e. a girl "working" in a bar, usually with unnecessarily revealing skirts and tops.

Has its origins in South London; etymology rumoured to be an oft-absent headteacher caught soliciting in the late 1970s. In order to avoid direct reference, the claim that he was doing his 'duty' evolved into 'headmaster's duty'.
I think she's probably up for a bit of headmaster's duty
