A middle-distance relationship, or "MDR", is when two people find themselves living with *JUST* enough distance between them that they can’t see each other as often as they'd like — shorter than the distance between Taylor Swift and Adele's vocal ranges but longer than the time it takes to master the catchy lyrics to Tay Tay’s latest chart-topper. Commonly used for a relationship with a significant other, friend, or friend's pet that lives more than 30 minutes, one bridge or a very large hill away.
Person 1: How often do you see your BFF?
Person 2: Um, like once a month TOPS. She lives all the way in Oakland.
Person 1: Ew. I hate crossing the bridge.
Person 2: I know, but I love her. She makes having a middle-distance relationship totes worth
