This gem begins by taking an egg and inserting it into your partner's anal cavity. You shall then begin to ass rape your partner with reckless abandon to the point of creating enough heat friction to boil said egg. Once egg is boiled through this process you will punch partner in the kidney at which point egg well be passed. You shall then take egg and crack it open on partner's forehaed and exclaim "Welcome to Potomac Fuck Face". You will then feed egg to partner.
