normally girls don't treat because the men are supposedly
supposed to be more financially capable compared to women 
although they say we're living in a society of equal status,
lets face it.
his money is my money.
her money is her money

ok i'm stereotyping
i know not all girls are like this
this only applies to money leeches 
for people who play DotA, these women are classified as a new
hero called, Lich Queen.
saying us women financially uncapable ? .. you will never
find a girl with that attidude ah ...
