When he tries to teach his dull childhood friend the art of orgasm, he is interrupted by the sound of a slap, followed by a "shoop" and a "clacking" . He realizes that he has just witnessed "the most important part of sex" and wonders why he remembers such a thing so suddenly. He tries to explain to his friend that he sees "twitch" and "sigh" , but he is unable to explain what he is referring to. He asks his friend to go ahead and slap the "swallow" and then "cum inside twitch" before he is able to do so. He tells his friend he has cut him off and asks him to go home.
