I don't live to work, I work to live
And live at the weekend
And maybe spend a week in the sun
I come home, wet the bed
Throw my sheets out the window
Then Sunday morning comes
Here's the crux of the song: 'I don't live to work, I work to live, and live at the weekend' - A career is not a priority for them: they only work to get money so they can enjoy life at the weekend.
This is followed by a fairly disgusting admission of crashing home, wetting the bed and throwing the sheets out the window. Again, there's that pride in the destructive powers of alcohol - and still it's followed by 'I can't wait for my next drink'.
