This has nothing to do with a wrestling company shilling its merchandise to the fans. Rather, it's all about a wrestler shilling another wrestler's move set. In a wrestling match, the idea is to try and make the match look and sound believable. That means when a guy gets slammed or put in a submission hold, he needs to make it look like he's in a lot of pain, or otherwise the move doesn't look very effective. Selling helps promote not just how deadly a move is, but also how threatening the wrestler is when executing the moves. If a wrestler doesn't sell a move, it weakens the move and the fans don't believe it as being an effective attack. Sometimes a wrestler will perform a "no sell" during a match. This is done to show just how dominating one wrestler is over the other. One example of no selling is when The Ultimate Warrior got right back up after taking a Pedigree from Triple H at WrestleMania 12. Then there's overselling where the wrestler has an overreaction when taking a particular move. If you ever watched Hulk Hogan versus Shawn Michaels at SummerSlam 2005, you'll see many examples of Michaels overselling Hogan's moves to ridiculous levels. The ideal way to sell is to find that happy medium. The wrestler doesn't want it to look goofy, but at the same time the move can't be as effective as a slap to the face. The best wrestlers know the right amount of visual and audible cues to give for certain moves.
