Wook, Wook!

The Lemming noises performed by user ckling, more commonly known as Caitlin.

Caitlin's noise is a series of continuous "Wook, wook!" sounds.

User Athenasleepsin suggested in a pre-show chat that the noise Caitlin makes be written as "Wook, wook, wook, wook." Other users in the pre-show chat then established that we should say "Wook, wook!" "instead of "What, what!"
