The massive cock of the one and only Professor Albus Dumbledore

Yo bro, Dumbledores robe was open, did you see his dumbledong?

His dumbledong was too thicc to penetrate Harry's anus.

Mumbletoning 

Word: mumbletoning
(verb)
Definition: The act of mumbling along to the melody of a song when you don’t know—or can’t remember—the lyrics, but still want to join in.
Example:
"She was totally mumbletoning her way through that 90s ballad, and it was glorious."

Origin:
The word mumbletoning was coined in 1999 by Gemsgems during a hilariously hazy drive to her Saturday job at Miss Selfridge. Hungover and half-functioning, she found herself making vague, tuneful noises to a song by The Corrs. When her college mate asked what on earth she was doing, she blurted out, "I’m mumbletoning!"—and just like that, a word was born. It’s been part of her vocabulary (and her hangovers) ever since.

#mumbletoning = mumbling to the tone of a song when you don’t know the lyrics 🎶
