An attractive boy or group of attractive boys used by a small group of girls for the sole purpose of showing off. The girls don't necessary like to be around the boys they are just there to look cute. This is a female version of arm candy.
Person 1:Man! would you look at those broads with all those cute boys!
Person 2: Aww they ain't nothing but a bunch of showboats.
A man or woman that takes joy In fucking in public places, usually in plain site. You'll most often see the Memphis Showboat in public parks, Jack Pirtle's Chicken parking lots, or Picadilley Cafeteria buffet lines.
Look at those Memphis Showboats over there fucking on top of that statue of Robert E. Lee.
A phenomenon in film/television series, most notably streaming series, where the main premise is drawn out to such a point that it takes an entire season or more to get the parts of the series the audience is actually interested in seeing.
For example, if a series is titled "Surf Dracula," a majority of viewers would tune in expecting to see Dracula surfing by the first or second episode. However, the entire first season would instead be tedious padding and backstory before finally ending with Dracula surfing in the last five minutes of the season finale.
I watched "Smallville" on Netflix the other day. Dude, it was ten seasons of filler before he finally flew! Major Surf Dracula Syndrome!
