The opposite of a tally whacker

A typo by Stephen King

In New Zealand this is what my son calls a bommy knocker

It’s when one boob is much bigger than the other.

Sounds like a British sex term

A bommy is a small metal plate attached to the side of old wooden ships. It would be attached outside the ship a few feet above the water line. A metal knocker was fixed to the bommy with a small float. If the ship started to take on water or loaded to much cargo, the ship would sit lower in the water and the knocker would hit the bommy, alerting the crew of potential problems.

Sounds good at least...

Never heard it before. I googled it in incognito tab, just in case.

Looks like a mace.

It's a flail. Like a wooden stick with a chain and a solid metal ball on the end

Knocks boms

A sort of monster with a butt fixation.

An insult, a sex act, and/or a drink.

Sounds like gin and tea, served hot with a twist of lemon.

Made up nonsense.

Some kind of door knocker?

A blocker? (Sports or hormones?)

Thinking rhyming slang.

British schoolyard game

a right ass I'll bet

gibberish phrase from a children's story i don't know?
