casket base

The opposite of a basket case.

Instead of being frazzled or overwhelmed even in trivial situations, a casket base is steadfast, cool, collected, and on top of their game even in dire, solemn situations.

Reliable in the “come in clutch” way

“I was a total mess at the picnic, I was losing things left and right!”

“Total basket case, I know.”

“Wish I was more of a casket base than a basket case.”

“Never heard of it but I think I get what you mean.”
