Whilst fornicating with a partner who is impared in the limbs department ( a quadrapolegic usually), you put on a clown costum and tie her to the ceiling fan and turn it on. Once she gets up some good rotation on her you bloody your cock up in one of her stumps( your choice) and wrap it in bubble wrap before agressively stabbing ( mike myers style) it into her vagina.

to sport a boner, fly the sail at full mass, rock hard, etc.
