Maybe it' make sense to split the phrase into two separate words?
What would you suggest for "pogoähnlich"?
It is not a real pogo infront of a stage while a band is playing.
It can happen on a party and last for a couple of seconds and then it's over.
It can be giving one or two bodychecks or a short embrace slightly and afterwards pushing each other away.
It can be another kind of music than punk or even without music.
And what would you suggest for "Spaßrangelei" when people pretend to be in a fight but they know each other and are friends?
@ no me bré, @ dude:
mosh, moshing or German moshen or moschen was related to the metal scene, definitely. I was born in 1966. We had those discussions as teenagers in the beginning of the 80s. It is the same for headbanging, headbangers etc.
I would even call moshing and headbanging synonymous. But words can change their meaning over time.
Stage diving comes from the hardcore scene, either US or Canadian. We should ask Henry Rollins.
I am not sure about "crowd surfing" and "wall of death".
