I'd kind of like to introduce DCP as an acronym.

[SpringchickenGoldBrass]

Meaning 'Dear Co-Parent'. I can't be the only person with a perfectly amicable but not sexual/romantic relationship with DC's other parent. And am fed up of typing 'DS' dad' and arguing with myself about the apostrophe all the time.
Mind you I have been thinking about whether there might be a better term than co-parent.
Child's Other Parent Who Is Not My Partner? That makes COPWINMPY. No, that won't do. Acronymic cheating could make ChOPWIMP (CHild'sOtherParentWhoIsn'tMyPartner) I suppose. Hmm. So me and Chopwimp took DS to the park...

Nice Co Parent. Although that could get confusing with multi storey carparks that charge £1 for every 20 minutes.

SlightlyJaded: DSD is already in use on here at least for Dear Step Daughter. And DEX won't really do as co parents are not always ex partners.
But keep 'em coming, folks

Oh and I wasn;t attacking any particular poster over the use of Manshape, I have seen it used elsewhere (eg not on MN) and loathe it but like someone else said, it's a matter of taste.

You are being unreasonable, I refuse to learn any more bloody acronyms. How long does it take to write my son's dad?

My vote goes to Chopwimp.

SGB Oh yes of course it is

Dammit, seemed so simple.

OK I'm with chopwimp :o

Oo-er! DCP is my DEX's rl initials
