Well if he did he pinched it from Eddo Brandes.
And I bet Eddo Brandes pinched it from someone else ! Although Eddo Brandes apparently said "every time I shag your wife she gives me a biscuit" and having analysed the insult, I have come to the conclusion "every time I shag your mum she gives me a biscuit" works better.
Because not only do insults against someone's mother generally work better than against their wife, imo, but the proposition that it is a much older woman links in well with the suggestion that the biscuit is a reward for a favour.
Which all reminds me of an occasion many years ago when I was working alongside a young carpenter not long out of his apprenticeship. Earlier in the week I had, in the course of general chitchat, mentioned that my mother had gone on holiday to visit my sister in Spain.
As we were working, in an attempt to wind him up (if I remember rightly his girlfriend was pregnant) I called out to him, "what's up mate, ain't you getting regular sex ?" without a hesitation he retorted, "No, not since your mother went on holiday"
'Twas the best put-down I have ever had said to me – I had clearly met my match 😀 And whilst I haven't worked with him or seen him for about 15 years now, I'm still occasionally in contact with him and we now exchange insults via texts messages 8)
