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.
