She's got old pants is a bucket

The story:

I was singing loudly on the school bus on a visit, and then this
song came on, and obviously it's the first line so I started
singing so loud and my friend was like:ahahah an what did you
just say, and I said: she's got old pants in a bucket and then
she showed me the actual lyrics and I was so embarrassed,
apparently I went so red, but not only that, the whole bus,
which had quite a few teachers on two, heard me singing
too!!!!!
