noun - e.g., "to have a Monroement"
The unfortunate moment, while walking down the street, when a loose and flowy skirt gets blown up by a strong wind, exposing the wearers panties.
The word derives from Marilyn Monroe's skirt blowing scene in the 1955 film The Seven Year Itch.
I knew I shouldn't have worn my silk skirt today. It was *so* windy downtown, and I totally had a Monroement as Suzanne and I were running to catch the MAX. Everyone saw my thong, and it was very embarrassing!
