Slug Club

"He used to handpick favourites at Hogwarts, sometimes for their ambition or their brains, sometimes for their charm or their talent, and he had an uncanny knack for choosing those who would go on to become outstanding in their various fields. Horace formed a kind of club of his favourites with himself at the centre, making introductions, forging useful contacts between members, and always reaping some kind of benefit in return..."

- Albus Dumbledore on the Slug Club

The Slug Club is an informal name for Horace Slughorn's favourite students at Hogwarts School of Witchcraft and Wizardry. Slughorn taught Potions at Hogwarts during two different stints; both times, he singled out students he thought had potential, either because they had influential relatives or themselves possessed fame or talent of some kind. He invited these select students to parties, notably to a lavish one at Christmas, and kept in touch with them even after they had graduated, as they could provide him with insider information or various luxuries.

Meetings
"A toast, to Hogwarts' brightest and best!"

- Horace Slughorn

During the course of the school year, Professor Slughorn would hold various get-togethers of the club. These were usually dinners with fine foods, during which Slughorn would lead conversation in order to get to know the members better and to encourage them to associate with one another as well. Sometimes he would invite famous former members in as well, such as when he introduced professional Quidditch player Gwenog Jones at a dinner in 1996. Slughorn's hope was to cultivate talent and to give his favourites "leg-ups" in their careers, hoping to reap the benefits of being connected to them once they became the "highfliers" Slughorn expected them to be. These benefits came to him in various forms, such as being able to recommend people to Ministry of Magic positions to receiving various gifts and perks, such as excellent seats to any Quidditch match he cared to attend.

On December 20, 1996, there was a lavish Christmas party for past and present Slug Club members held in Slughorn's office at Hogwarts. It was the only get-together of the club that Harry Potter attended, and reluctantly, at that.
