Halls of ivy

[Barnhart]

Perhaps, one of the most absurd examples of this sort of "etymology" is
that for _posh_.  That one is memorialized in a song in the movie
entitled Chitty-Chitty-Bang-Bang.  This one has been so often proffered
that it has too be given space for debunking in etymological
dictionaries (cf. The Barnhart Dictionary of Etymology).
