Loitering while walking. Hanging out in an environ, i.e. a particular block; moving so as to avoid arrest on more traditional loitering charges. Mopery is not a real charge or violation of the law, but a descriptive term, stretching the legalities of loitering, which would include staying in one place.
quasi-criminal offense frequently enforced by cops in crowded areas such as concerts and sports events by stating "move it along ..there's nothing to see here...."
Before Paul got a chance to see what was going on he was charged with "mopery with intent to gawk"
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!
