Cyber Hunting
Similar to cyber stalking, it is when one, usually a male, uses social media as a sort of hunting ground to find and select someone they find attractive with the hopes of engaging in sex. Once their prey is found, they will pounce on them and proceed to send them unsolicited sexual messages and/or pictures of their genitalia. What makes it different from regular stalking is that the intent of the person is obvious and they do not try to keep their distance as a stalker normally would. They will often instantly message their prey the moment they spot them and will continue to message them despite receiving messages that explicitly ask them to stop.
That guy has been on Facebook for the past hour and all he's doing is clicking on profiles of pretty girls and checking his DMs. He is obviously cyber hunting. What a fucking creep.
