brass monkey
While the exact origin of the term 'brass monkey' is unkown, it's 200-plus year usage history indicates its original meaning is related to the Kelvin Spheres that sit on either side of a ship's binnacle. The balls, which are iron, help offset magnetic shifts so the compass inside the binnacle remains pointed toward magnetic north. The two balls are traditionally mounted on brass arms, which were called 'monkeys' by sailors in the 18th and 19th centuries. The phrase 'cold enough to freeze the balls off a brass monkey' didn't rear its head into common usage until the 20th century. Original uses referred to 'freezing the tail of a brass monkey,' or 'melting the nose off a brass monkey,' and can be found in 19th century sailing texts like Herman Melville's "Omoo" ('...it was 'ot enough to melt the nose h'off a brass monkey....'). Again, while the exact meaning is unkown, the term has beeen definitively rejected by the Department of the Navy, the Oxford English Dictionary and other noted etymologists as describing a pyramid of cannonballs on a brass tray. Not only were they never used on board ship during the age of sail as they would have rolled everywhere with the rocking of the ship, but the balls and tray would expand and contract at nearly the same rate due to cold and heat, and therefore the stack would never have fallen apart due temperature change.

Loved the mug! It really suits me, my co-workers love it.
Pissah!

nice.
Sent this to my crush now she has a restraining order on me!!!
Without this mug, my life was but a series of painful unfortunate events. Since it has come into my life, love has followed, joy has followed and dishonour has been disavowed. Sincerely. From the bottom of my heart. Thank you. Please keep up the good work and I hope everyone will find joy as I have one day.

Just wish it could have had a little more of the text on the mug, but otherwise it's great. What a clever marketing idea to be able to get this on t-shirts and mugs.
I spent the money and directly sent this to be the pettest person ever to a person who was doing this to me. It was awesome
It’s a sturdy ceramic mug. A little pricey, IMO, but I really wanted this definition on a mug. ¯\_(ツ)_/¯

Just what is needed for someone’s desk during the pandemic and beyond when they have to “MacGuyver” to make things happen.
Best purchase of my life, it's all downhill from here!
