I saw this game in Twilight series club,credits to hellgirl223.
So you have to pick a character to hug, kiss and slap, after that write 3 other character names from Harry Potter and a user must pick who to kiss, hug and slap from the names you wrote, and then the game continues..
Example:

TheDream:
Kiss: Harry Potter
Hug: Bill Weasley
Slap: Umbrige

Ron
Hermione
Pansy

SunAngel:
Kiss:Ron
Hug:Hermione
Slap:Pansy

Lucius
Fred
Luna

and then the game continues...


Hope,you'd like it!
