The act of having sexual intercourse with everyone on the planet... at the same time, whilst watching an episode of the hit comedy 'friends'
It is also not unusual to grow several detachable penises after u get to the one millionth and one base.
Richard: Dude i got to the 1000000th base last week!
Paul: What! that means you had sex with me! and my mum?! and my dad!!! you fucker!!!! What friends episode were you watching?
