The act of smearing Marmite on your balls, for your dog to lick off!
Guy 1: I had a Marmite Dog last night.

Guy 2: what the hell are you on about?

Guy 1: Yeah! I smeared Marmite on my bollocks while I was whacking off, then I got the dog to lick it all off!

You first invite a random girl over to your house. Whilst waiting for her arrival, you eat marmite (on anything) until full, and drink plenty of water. When she arrives you proceed to go down on her. The naturally occuring stench and taste from between her legs will make you throw up all over her vagnina, and the mess will resemble that of giving birth and smell of marmite. Hence the name, marmite afterbirth.
I just bought a new tub of marmite and invited that fat stinker over from last week. she's gonna get such a marmite afterbirth.
