Speidiship 

A relationship that is obviously without real feelings; a fake relationship

Art and Glenda are in such a Speidiship: she uses him for his money, and he just thinks she's hot.

Spendship 

A situation where you are stuck shopping with a "friend" who only likes you for your money.

I thought it would be a fun trip to the mall, but my day with Jane ended up becoming a spendship.
