Jeff: Park's closed!

Dog park close

A degree of relationship to another person. The person is more of an acquaintance that you’ve met, but don’t know outside of a specific context. You may have exchanged pleasantries, not exactly superficial, but probably not intimate details. Sort of making conversation to pass the time.

I saw you speaking with Mary the other day. Do you know her well?

No, not really. We are dog park close.

We met at the park and spoke often. I wanted to know her better but we never really got beyond dog park close.
