evil

I'm a little stuck... Click here to teach me more about this clue!

'it's wicked' is the definition.
(similar in meaning)

'live it up' is the wordplay.
'live' anagrams to 'EVIL'.
Though, I am not sure how this is indicated.

'to' is the link.

Can you help me to learn more?

(Other definitions for evil that I've seen before include "Wicked - vice" , "Badness, depravity" , "Demonic" , "Morally corrupt" , "Profoundly wicked" .)
