When you bang someone of the opposite sex for the first time and add them onto your lifetime list of girls you have "plus oned". You cannot plus 2. If you have sex with two new people in one day or in one encounter it is then labelled as having had two "plus ones".
I took that girl home from the bar last night. I got a plus one. She was a HO. FO SHO.
