Do the world a favour

You madam are a skidmark in my favourite boxers
A pimple on the face of life
I look at you and I question reality
It's made debate suicide once or twice  
You are an ingrowing toenail
A brick in the shoe
So cock sure but you haven't a clue
If there was a prize for idiocy you'd get first place
When the hunt for brains was on you must not have joined the race
Please don't breed do the world a favour  
Better still jump of a cliff with you're stupid behaviour
