"Smell my cheese", the bully would invite. Cheese famously smelling delicious, you would eagerly bend over to the waiting fist, anxious to see if there is a tiny cube of fragrant cheese concealed within. As you get closer, you become suspicious. There's no cheese here... and then, the bully would punch you in the nose. A pleasing variant of this is when the bully adds "Smell my cheese, would you?" and walks off huffily, as though you've offended him mightily. You are the victim of another imaginary foodstuff.
