Why did you censor “sack”? That’s not even a foul word.

It's a variation of "grow some balls": https://en.wiktionary.org/wiki/grow_some_balls

I know that. I just don’t understand why you’d censor it. This isn’t Club Penguin.

I don't think it is meant as a censor, but to be illustrative.

Illustrative of balls? That’s a new one.

If that were the case, shouldn't it have been 's@@ck'?

Excellent point.

It has since been edited, so apparently that was the point.

Mystery solved! Wonderful investigation, all.
