Very clever.

I am fairly certain that it is pronounced "s", not "sh". It's just a double 's', such as in 'heiss' or 'Essen'.

I’ve never heard ß pronounced ‘sh’. Maybe in the East where they speak weird

Except it's not true. ß is pronounced like a regular "s". Sitcoin.

as well as ß being the same as the expanded "ss" there is no C in german, only K and S. there is also no "oi" dipthong in german, nearest is 'eu' as in 'feuer'. spelt in strict german rules it would be schittkeun

Much like BSV, I didn't verify.
