How do you pronounce SPAC?

Exactly how it looks - “Spack”

Unfortunately, in the UK this is a deeply hateful term for disabled people. Actual hate speech if you couple it with violence etc.

What's the old saying? Two cultures divided by a common language..

I came across "spack"[1], another unfortunately named repo recently as well.

Another good one is "nonce" - seen frequently in oauth and crypto - always gets a laugh out of the juniors.
