That’s just how the toilet flushes

How things turn out to be or come to be.

Synonym - that’s how the cookie crumbles

Joe - Why did today have to be the day she left me?!? Why!!!
Me - Man that’s just how the toilet flushes sometimes bro.

It’s that bit of poo that no matter how well you flush, it breaks off and comes back.

Just left a flush bundle in the staff room toilets
