What ever does this sentence mean? Bad as each other is not meaninful to me.
You forgot the first "as".
"as bad as" indicates a comparison.
The standard of comparison is "each other".
So I am as bad as you, and you are as bad as I am. We are as bad as each other. We are equally bad.
I always thought "as bad as each other" was a common turn of phrase UK-wide, but as I am half-Welsh, maybe that's had an influence!
This is a perfectly normal UK English usage.
