Flag Collector 

Engaging in sexual activities with people from different nationalities. Instead of 'notches' on the bedpost you are collecting different 'flags'

I slept with an Irish lad on Tuesday and last this morning I woke up beside an Israeli man. I collected two new flags this week, so after last weeks Scottish bloke I really am turning into a flag collector!

Routine engagement in sexual contact with foreign-born partners, with the goal of adding a new nationality with every sexual encounter

Billie took up flag collecting at the party, having had sex with a Colombian girl early in the night, and making out with a French girl later on.
