These used to be the ultimate symbol of “Spießertum”. Funny how things change and trends come and go.
"Spießertum" I'm getting the translation of philistine, which seems a bit harsh? Anything that better captures the flavour, for an Anglophone?
You could also call them submissive, hypocrite squareheaded cowards.
The "Spieß" seems to translate to "skewer", "spit", "pike". So, they sting, but are not very sharp. They always side with the authority du jour, because that keeps them safe.
