Bi- for show

When a girl claims she's 'bi-' or 'bi-curious' just to attract the attention of another girl to either turn her boyfriend on or attract other guys. Usually happens at swing clubs or in bars after midnight. But when the time comes to 'put-up or shut-up' she turns shy and backs off.

us: She's hot and says she's bi- but her boyfriend is just ok, let's get a room and you 2 girls can have some fun.

them (after we get the room): 'I'm not really bi-, I just like to play with girls on the dance floor'.

us: Damn, that bitch was just 'bi- for show'
