Sometime ago, my wife and I were watching an episode of Friends and one of the issues afflicting someone in the cast (Ross, to be exact) was having to "define the relationship" with a girlfriend of his, or DTR, as my wife informed it is known in the Christian circles.
Since I didn't grow up as a Christian (As a good Cuban, I was raised Catholic), I had no idea of such an acronym. In light of that, I think we should come up with some new ones.
AWIAR? - Are We In A Relationship?
OWLM - Our Worship Leader is a Metrosexual
MPBY - My Pastor is Better than Yours
DBD - Dan Brown is the Devil
BYOB - Bring Your Own Bible
Can you think of anymore?
