When a partner is wall twerking naked and the other partner is at the top of the wall and jumps down onto the person wall twerking and tries to insert his penis into the anus while falling towards the person. There is a 90% chance of breaking your penis if attempted
Doctor: How on earth did you break your penis so badly?
Patient: The flying spider
