I will not refer to Kingsley Shacklebolt as a "Big Black Sex Auror"

Of course, it was commonly assumed that the aurors guarding Hogwarts when Voldemort was out there and up to whatever he was up to was a good idea. A marvellous idea, actually, everyone felt safer that way, and there was no doubt that way more parents would have taken their children out of school if this measure wouldn't have been taken.

However, there were complications that no one had foreseen.

"I should really think that you were mature enough to stand above this kind of behaviour", Professor McGonagall announced in class. Again, some pupils who luckily remained anonymous had been out to the borders of the ground where the aurors were stationed and amused themselves by encouraging their guardians: "Go [insert name of auror here] go!", was the most uncreative way, followed by "Oh gosh, there's a butterfly trying to cross the border! Get him! GET HIM!" Others were singing random songs about guardians, some with altered lyrics, some not, or commenting the auror's patrolling like a sports game (the magic megaphone had mysteriously disappeared after the last Quidditch match, for, it was generally assumed by both shocked teachers and grinning students, exactly that purpose; however, it reappeared before it had been in use, and no connection was ever proven).

Parvati and Lavender burst into helpless giggles. "Miss Patil? Miss Brown?", the teacher asked, tightening her lips disapprovingly. "These aurors are here to protect you. I do believe they deserve your respect." Parvati couldn't help herself. "But we do respect them. Especially the big black sex auror." Both girls almost fell off their chairs with laughter they couldn't fight back, and this time several other girls joined in, though mostly hiding it better than Parvati and Lavender.

Professor McGonagall, however, was not amused.
