When a man is nearing ejaculation, his partner must say "Abracadabra" (or "Accio" for the Harry Potter fans) and tap the head of the man's penis with their index finger, or wand if available. Upon tapping, the man will ejaculate onto his partner's face creating Merlin's Mist.

He's the greatest wizard of all time. He is also known as Emrys. Everybody just loves him as he's the sweetest, funniest and cutest person to ever roam the Earth. You would have to be an idiot to let him go.
If he is your friend, he will never leave your side, even in your darkest moments.
He's also a savage dragonlord.
