Its a Russian hooker special sex thing called the "Wait for thunder, Bushka"; (1) Hooker finds a John (Dzhon in Russian) so engrossed in his cell phone twitter account he never looks up; (2) she drinks a quart of rotgut Vodka, (3) Pisses in his ear all the while while screaming "That's the rain, Bushkat! Rolling Thunder's on its way!!"
