Describing a person's long-winded story that is either a go-nowhere diatribe or an ill-fangled tangent that goes on and on to no end or point. A proper story between friends is an ABC or XYZ story. A beginning, middle, and end. An LMNOP story is completely meandering, all filler and fluff with no structure. A waste of time.
Nick: Hey Bill, did you listen to Ralph's story he was trying to tell? He must be on coke or something.
Bill: Yeah, he was straight LMNOP on that one. I had no clue where he was going or ending with that story. I'm glad I walked away.
Girl: What does the ABCDEFG mean?
Boy: A boy can do everything for girl
Many people told the girl that there have HIJK.
He is just kidding
Girl smile and said: it's fine. Because LMNOP is after that.
Love must need our patience
