Script (guión): Idioms, ‘can't do it for toffee’. If you can't do something for toffee you are incapable of doing it properly. We went out ten pin bowling yesterday which I'd never done before and it turns out, I can't do it for toffee. At one point I threw the ball and it flipped up, missed the lane completely landed on the foot of a lady next to us, broke three of her toes and they asked me to leave. So next week, I'm going to try golf.
