From 'beefish' + noun suffix '-ness'; double-suffix construction combining '-ish' and '-ness' to describe approximate beef-like qualities.
Words with double suffixes like 'beefishness' show English's flexibility—we can stack meaning-making tools together, though stacking too many makes words sound ridiculous, which is probably why 'beefishness' rarely appears.
