Also from southern UK and we called it knock down ginger. Looked it up and found this:

Where ginger is to move “gingerly” i.e. cautiously or carefully. Can’t comment on how valid that is but that website says the term has been in use since the 19th century.

I found out the other day this is being referred to as Mar-a-Lago face. Search it up if you like; I don’t want to link to any news rags (Independent, Huffpo, etc), who are the only ones writing about it.
