NBF/NGF 

Non-boyfriend/non-girlfriend; someone that others assume is your BF/GF, but neither part has made it official or wants to put a label on the relationship.

“Should I get my NBF a Valentine’s Day present?”
“Should I introduce my NGF to my parents?”
“My NBF/NGF is gonna meet us at the clubs.”
