spendaties 

When you have money that you want to spend, but don't really care what you spend it on.

Oh man, I've just been paid and I've got a real bad case of the spendaties!

spendies 

Leftover money for frivolous activities with your friends on the weekend.

When your friend pays you back from dinner the last before: "Oh, spendies!"
