Shame, and I was this guy’s only Facebook friend.
After this, I decided that engaging in a conversation defeated the object and after that did not engage further than a few words, never to be drawn in again.
Fuck off is the end of a conversation, not the beginning.
(Lesson: For my international audience, ‘poes’ is a derogatory Afrikaans word, similar to ‘cunt’ in English. It is probably of a sexist and mysogynistic heritage highest insult you can give someone is to call them a female body part and rather unfortunate, because cut is cool and poes is awesome. And it is a lovely word to say. Like fuck off.)
