Excuse me, but can someone please explain to me what is a fiscal conservative/social liberal?

This definition baffles me completely, according to my understanding and I am not an expert either in politics or economics, it is a complete contradiction of terms. Maybe it is my English?

In my dictionary, it is not enough that someone is pro choice and/or pro gay rights to label him a liberal, it can make him a good old fashioned conservative NOT a fanatic religious/self-righteous one.

Please help, thank you!
