Similar to a whatchamacallit or a thingamagig. Used to refer to a thing whose name one can't place or has forgotten.

I pulled the domaflogie to turn on the light.

Doumaflage 

Noun, French slang: a placeholder word to describe a person when you can’t think of their name

“Ah c’est quoi son nom? Doumaflage me doit de l’argent!”

Hey what’s his name? Doumaflage owes me money!
