kakushka
It’s Russian for poop, but way more intense like when you’re stuck in a bathroom for three hours and it’s still not done.
My aunt called me a kakushka because I took forever on the toilet.
He said, 'You’re the kakushka of the year!' after I clogged the whole restroom.
She texted me, 'You’re a kakushka, I’ve seen horses go faster than you.'
