overbalances

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

'loses equilibrium' is the definition.
I can't judge whether this definition defines the answer.

'excited as lover can be' is the wordplay.
'excited' indicates anagramming the letters.
'as'+'lover'+'can'+'be'='aslovercanbe'
'aslovercanbe' is an anagram of 'OVERBALANCES'.

Can you help me to learn more?
