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.
