“Bugger this.”

“Excuse me?” Standing at the head of the classroom, Severus gazed down at Longbottom in time to note that his cauldron was mere moments from a dangerous overflow. Wand dropping into his hand in an instant, he waved the whole mess clear, vanishing the contents even as he strode up behind to the young man’s table and snapped, “Nevermind buggering, you botched it.” 

Despite the fact that if Longbottom hadn’t spoken out in class Severus might well have missed the pending disaster, he carried on sternly, “And that’s no way to speak in class. Now, can you tell me where you went wrong?” Judging from what he’d vanished, there were several points, but what mattered was whether Longbottom could identify any of them.
