An extract from the PortraitParty sharing page. Like it (I mean, me like it. You can too if you want!
I realised tonight, probably whilst emptying my bladder of a large quantity of Californian Chardonnay, that there is a form of portraiture which hasn’t yet been covered by your site.
Let’s call it ‘The Portrait Slam’ (as in a Poetry Slam) where two individuals take turns at (fondly) demeaning each other through satirical gags of a visual nature.
This can be seen in the follow back-and-forth between myself and Cuffe on IFN.
First the Cuffester does his en-garde move by portraying me in my naff PJs
I counter with him pleasuring a crocodile
He then gives me the voodoo treatment
And I tell him where to put it: 
To be honest, most of the ladeez on the site are quite happy to give Cuffe his cuffeupance
And perhaps realising he’s ultimately doomed (though aren’t we all) Cuffe commits illustration-hari-kiri on himself
BTW. I know you’re mainly a portraitist, but we’d love it if you could spread a bit of Rama sometime on our IFN-toast.
Regards
Steve
