one of the many Hobbit themed cocktails available at the pub of the same name, in Southampton. Contains vodka, archers, blue WKD and lemonade. Very refreshing. £3 for a pint. I love them far too much.

Blocking the passage of something through use of wizardry and copious amounts of staff waving. Also, basically just not letting anything through, ever.
Dude, the Republican's are totally Gandalfing Obama's every move. It's like they just don't like him or something.
How did your date go?
It was great, but she totally Gandolfed me at the end. I think I saw her delete me out of her phone after i tried to give her a good night screw.

Sam: I was up all night. I might have to take a nap after breakfast.
Bil: No dude, just take a hit of gandalf and you'll be able to at least make it through second breakfast, elevensies, luncheon, and afternoon tea.
Pip: You shall not pass out.

The greatest wizard in the world (Middle-earth) he's so cute and adorable! Everybody should have a gandalf in their life! Someone they can talk to, someone who can always offer you advice, someone with magical powers to save u from all the baddies in the world, someone who you know will always give you a hug at the end of the day!
