Jeans that come already "expertly ripped." It ruins what ripped jeans used to be. Ripped jeans used to have a story behind them. For instance, you could have ripped those climbing a fence escaping from your gf's dad.
John: How'd you get those rips on your jeans?
Richy: Well....I'm so cool that my jeans came pre-ripped.
John: You bought pre-ripped jeans. You must be really cool....
