Chick of teeta, tell me what's wrong.

The story:

I was watching an abba documentary on TV and my
sister happened to come into the room and this
song came on so I started to sing along "Chick of
teeta tell me what's wrong" and she was "LOL
Fail!" I was corrected then.

Often wondered who this chick of teeta was and
knowing a lot about wildplants, I came to the
conclusion that it was about Coptis teeta, a rare
type of buttercup used in Chinese herbology and
this "chick" was a metaphor for something, man that's embarrasing. Should have looked up the
lyrics but not knowing the real title and typing
in "Chick of teeta" to a search engine gets you
webpages about chickens teeth...
