This is mahogany

A phrase used to describe something ridiculous or upsetting, perhaps both. Saying "this is bullshit", but in a nicer way. A way to express frustration on something inconvenient or stupid.

Elton: "Hey, heads ups. The registers are down again."
Reign: "I thought they fixed that. UGH! This is mahogany!"

Or

Roxy: "Wanna play on the switch when we get home?"
Xyrein: "Mine is broken. Has been for months."
Roxy: "Months?! That's mahogany, what do you mean?"
