When someone posts something within social media to 'mark' their partner/territory, either directly or in response to a reference to or by said partner.

1. Jane (checking in via Facebook): Having a wonderful dinner with my man, Dick.

2. In a thread:

Tom: We should go to the strip club tonight!

Dick: Absolutely...I'm in!

Jane: Dick, why would you want to do that with me at home?
