A Ruaraidh is a large scottish mammal, often found in search for Guiness. It can switch from nocturnal to normal in a day. This is a skilled and friendly creature that has the ability to recall hundreds of LOST episodes at any moment.
If you are planning to keep a Ruaraidh, make sure you let it out to play football alot.
Ruaraidhs also, strangely enough, listen to the same music as prepubescent teenage girls.
Have you meet John? Hes a Ruaraidh when it comes to LOST.

Get the Ruaraidh mug.
Hairy mythical beast. Dwells down plugholes to feast on giant spiders. Often works as a librarian or book-shop owner. closely related to Bill Bailey. If you see one, run away immediately. They are very dangerous and quick over short distances, as they have stump legs and run like pidgeons.
The book I bought from Ruaraidh, it gave me clap.

Whats that coming from my plug-hole?? AHHHH ITS A RUARAIDH!!!!

Man, that guy looks like Bill Bailey! Its ok, its just a Ruaraidh. DON'T LOOK AT IT DIRECTLY IN THE EYES!!!
