I was just following a car that had two stickers on the back - one saying "kiss my arse" and a Betty Boop cartoon with her bum exposed, and the other saying "you've just been overtaken by a girl". (See attached pics if interested).
Is it just me, or is this incredibly tacky? I mean, the "baby on board" stuff doesn't bother me. But why oh why does anyone need to announce that they are female for the benefit of the car they have overtaken? Doesn't this just perpetuate silly gender stereotypes about women drivers? And why tell a random stranger behind you to "kiss your arse"? Is that really necessary?
Do you have such slogans on your car? If so, please could you explain why, so that I can put this issue to bed and move on with my day. 
(I've been disproportionately irritated by this today - can you tell...?)
