Overween (v) To miss the toilet when urinating.
My embarrassing moment of the day came when I was returning to the Underground bunker from the Brixton branch of Marks & Spencer with a bag of biscuits and tripped over a kerbstone, hurling myself bodily flat onto the wet pavement. I suffered a grazed knee and a bruised chest. I was touched by the fact that a nice Portuguese man came to my aid, as well as a colleague who had been walking behind me.
‘You should be careful,’ said the Portuguese man. ‘If you fall like that you can break your spectacles!’
‘Thank you,’ I said. ‘I shall bear that in mind when next I fall.’
I felt more stupid than anything else, and what further annoyed me was that not one biscuit had suffered so much as a crack.
