I'm scrabbling around trying to imagine what kind of accident would lead to the loss of a vagina, that tweet can only have been written by someone who hasn't got a fucking clue what a vagina is.
Well, quite!
"I was 'bombing' in a marine life centre and just as I hit the water, my vagina fell out and a shark snaffled it before I could pick it up! Bummer..."?
"I disassembled my vagina to give it a good clean and oiling but it squirted out of my hands and out of the bathroom window and landed on the head of a dog, who panicked and ran away! Bummer..."?
"I was practising an aria from the well-known opera Die Valkyrie, when a bat flew into the sitting room and was instantly killed by my high C! Desperate to conceal my crime (bats are a protected species), I stuffed the dead bat into the first thing I saw - my vagina, which was sitting handily on the chest of drawers - and popped my bat-filled vagina into one of the drawers! But now I can't remember which one I put it in! Bummer...
Something like that? I'm struggling here... But at least I've involved animals, which is always good.
