Shack Up

It's heartbreaking to see badly transcribed lyrics for such a tremendous funk tune (one covered famously by Mancunian postpunk band A Certain Ratio), so I present the actual lyrics (except for the one section I can't make out) below:

Wipe out the problems of our society Shack up! Shack up! Is that we can live together baby, unless we ? ? ? Shack up! Shack up! We can love together, work together, sleep together Shack up! Shack up! So why can't we live together & shack up baby, shack up?

We can talk about the wedding ceremony Shack up! Shack up! & I know it's just a phony Shack up! Shack up!

Marriage is a big commitment, yeah Shack up! Shack up! That you might find hard to live with Shack up! Shack up! I love you now, but that don't say I'm gonna love you forever Shack up! Shack up! 'Cause I don't believe in alimony or divorce Shack up! Shack up! So I think we should just split the cost & shack up, baby, shack up!

I can't figure out the second line - some online sources (like the one above) have the line "unless you can feel the heat." But it sounds more like "unless we man bee bee." So it might be that. But it's hard to make out, as the background singers sing "shack up!" over it.

It's definitely not "make a baby," as some lyrics sites have.

I am very surprised how many people miss the "alimony or divorce" line. It makes the most sense! "Alimony all day long" doesn't make any sense at all.
