Doesn't stand for anything really, it's just another word for girl/woman that is sometimes used in a derogatory manner Shleed always says it.
Bintje is a name, used ages ago for girls in a part of my country. So, one day, a primary school teacher came up with a new type of potato in 1905, and named it after his best pupil in class, Bintje Jansma. Bintje is a very popular potato here now. :lol:
