The coyote ugly of mail order DVD rental. When you place an item in your Netflix queue and forget all about it. One day the turd shows up you are shamefully forced to send it back unwatched.
Roomy one: A new Netflix arrived today.
Roomy two: Open it.
Roomy one: (opens it) All Quiet on the Western Front?!?! What the fuck!
Roomy two: Shit, mad queue regret man. I forgot that was in my queue! Gotta send it back and get the next Heroes disc.

-Girl 2: *screen shots, laughs evilly, and posts said picture on every social media they know of*
-Girl 1: "shit.. the Snapchatter's Regret is so real rn"

When you friend request a person on facebook who you dont know at all or very well and they bring up your facebook request in person and say they dont know you in front of people, making you look like a weirdo.
Blake turned out to be a total facebook regret. He made me look like a creeper in front of everybody, when all I did was friend request him to be friendly.
