Gandalf's Hair Dye 

When an old man with a very long grey beard braids his beard into braids and proceeds to shove the braided beard into a woman's asshole, leaves it in there for a few hours, and pulls it out, leaving his beard brown rather than grey.

Gandalf: my grey beard makes me look old
Frodo: go Gandalf's hair dye it
Gandalf: thankyou Frodo, can you help me unbraid it when I'm finished

2. (In the emotion/opinion) "Do you STILL think 80's hip-hop is cool?" "I'm George's Hair in the matter"
3. (As a noun) "Go on, have a cigarette Jon" "But I don't want to smoke" "Oh don't be such a George's Hair"
