" Son of a Banshee . That's useful" :D
" Dobby's socks !"

EXPECTO PATRONADS!

Hogwarts "'Yo Momma' jokes - link

yo mammas so fat the sorting hat placed her in all four houses. i laughed for hours, so funny.

"You filthy little Mudblood!" (Be like Mr. Malfoy here!)

If you know someone named Severus, you could call them "Snivellus" (like James!)

"Arrogant toerag" (like Lily!)

"Insufferable know-it-all" (like Snape!)

If you know someone who doesn't have great hygiene, you could say "_ would run faster than _(insultee)_ confronted with shampoo!" (like Fred and George!)

"Foul, loathsome, evil little cockroach!" (like Hermione!)

"You're mental!" (Like Ron!)

You could also do a Ginny. You know, when she took Ron down for not having a girlfriend yet. Something like that could work if you're feeling REALLY upset with someone.

And of course there is... THE ELDER SWEAR!! *dramatic music plays in the background*

VOLDEMORT'S NIPPLE! is an awesome insult lol

The elder swear is definitely the best wizard swear. EVER.
