coinversation 

Conversation involving or regarding money.

I'm running a little low on fundage so I'll have a coinversation with my moms and maybe I can go to the movies with you on Friday.

My boo had a little coinversation with me after I bought the Christian Louboutins last week so I'm gonna have to take it back to WalMartfor a minute.

Hey man, have you seen Donna? She asked me to loan her money for a week and it's been a month since then. I hate to get all loan shark on her but we need to have a serious coinversation.
