Mohs and I know that you’re an asshole.

Brass-3 Mohs scale rating… the same as calcite.

1. Pear shaped

A British expression used to indicate that something has gone horribly wrong with a person’s plans, most commonly in the phrase “It’s all gone pear shaped.” The origin is unclear, but one theory says that it is RAF slang relating to the difficulty of performing aerobatic loops, which were described as “pear shaped” if executed imperfectly.
