Translate this Vice City song?

I can speak and understand Spanish enough to understand and be understood. A poor legacy I have left mi abuela who raised me.

La vida es una lenteja
Sadly, the only lyrics I know for sure are:

Get up and open to the refrigerator.

Life is a lentil, you can take it or leave it.

And

Come over here little girl and move your body.
There aren’t many lines in the song but I’d like to know what they mean. Any body wanna take a crack at it?

Go see if the bologna fits…Yeow!

Ha! The ditty is dirtier than I thought.
