When a group of one sex encounters an attractive member of the other sex, one of them must flirt with them as an acknowledgement of there attractiveness.

Me and the guys were out last nast night and we came across Jenny who was looking phenomenal, so Adam gave her a courtesy flirt just so she wouldn't feel slighted.
