The latest cute name for disgusting behavior is sharking--where a man runs up to a women or girl in a public and pulls down off some of her clothing while another man films it. I would say this is assault, plain and simple--humiliation of women and girls for amusement--a message that you are not safe just walking down the street. The description of this as a "sport" is egregious. This is different from "pantsing" which is done between friends as a joke (like the infamous wedgie in reverse).
If you have any spare time please run a search and flag these videos as inappropriate. Like gang tagging, if material doesn't stay up long the motivation to produce it is undermined. It could also be flagged or voted down on sites like Digg. Feel free to leave some comments and contact the advertisers on sites that won't withdraw the material. If they don't care about women being safe on public streets they might care when their income stream is threatened. Look for advertisers that are large brands with active PR.
I am all for freedom of expression, but not when it comes to glorifying assault and sickos taking 'up shirt' filming to the next level. Some of the videos may be fake but I am not giving any benefit fo the doubt. If I end up looking like a humorless bitch I can live with that.
