I used to be love drunk, but now I'm an ogre

The story:

When I first heard this song, I would purposely sing it wrong to embarrass my 12 year old. I'd belt out "I used to be love drunk, but now I'm an old skunk (or punk, or whatever struck my fancy at the time)." Finally, I decided to listen and see what the words really were. Alas, my middle-age ears couldn't make out the words. The best I could come up with was "an ogre". I finally had to swallow my pride and ask my daughter what they were saying.
