Maykitten
A word used to call someone who is born in May. There is a superstition (not necessarily true) dating back hundreds of years ago; some people beleived that kittens born in may were useless as mousers and so used to drown them. Similarly, it was thought that people born in may were also useless. Maykitten was originally an insult, as it meant that the person was useless. But also, I use it as a cute nickname for a friend who doesn't mind any more =3
