Who's gabatootin my nasty groove?

The story:

I was in the car with my friend Dawn and we both liked to drive around singing loudly to music, especially older music. When that part came up I looked at her and informed her I had always wondered what gabatooting was and asked her exactly how one gabatoots a nasty groove. She started laughing so hard she cried and told me what the real lyric was. The funny thing is that we are known for making up silly lyrics to songs and what i thought was the real lyric was dumber than anything we could have ever come up with. To this day if the song comes on when we're around each other she still sings "gabatooting" and laughs till she cries. The truly sick thing is I have thought those were the lyrics since i was like 10.
