Hey everyone! I saw this in another spot and thought to post it here too.
So, the rules are simple. You spell your name or username with Harry Potter related things. Here's an example:

N-arcissa Malfoy
E-rised-mirror
L-estrange
L-ucius Malfoy
L-una Lovegood
O-cclumency
V-oldemort
E-xpecto Patronum
T-hree Broomsticks
C-hocolate frog cards
A-ndromeda Tonks
R-avenclaw
"T-roll in the dungeon!"
E-xpress(Hogwart's)
R-emus Lupin

Have fun!:)
