Looks like he is explaining how he gives a handjob.
My first thought was that Obama was explaining his adventures with TomInTib -
You know, when they went into Pokemonistan to apprehend OBL - then Obama explained how he grabbed Bin-Laden by the robe, and then jammed his Bowie Knife up under Bin Laden's rib cage to pierce his heart.
Obama then said he gazed into OBL's face and watched the life drain from his eyes - then he leaned forward and whispered 'Yippie ki-yay, mother****er' into Bin Laden's ear - the last thing he would hear before he slipped into death.
