a non boyfriend boyfriend, is a really close boy that you've been seeing for awhile and basically are dating, but don't have the relationship status
been seeing one guy for 6 months or more, go out, spend all free time together, hug, kiss, sleep together, just he isn't your 'boyfriend' so he's the non boyfriend boyfriend
