overslight 

to accidently on purpose forget to invite or include someone, and if confronted, feign innocence, so they can't be too insulted.

I didn't invite her to my party, i know i should have, but it was an overslight.

overnight activist 

A person who, upon seeing a political message on a social networking site, instantly becomes a die-hard supporter despite knowing nothing about the subject.

Jackie -OMG, I just saw KONY2012. Save the Children!!!!
Brenda -OMG me too. It's so sad that this is happening in Uganda.
Informed Individual- You know this has been happening 26 years and that the Ugandan gov did the same thing to get in power... overnight activists

overnight snub 

When you're messaging someone on a dating app and having a great conversation, yet after a night passes they no longer answer the next day.

Guy 1: "Dude I've been messaging this girl all night she seems great. I think this could actually lead to something"
Guy 2: "Bro that's awesome"
*Goes to sleep, 1 night passes*
Guy 1: "She's not answering anymore, wtf I totally got the overnight snub!"

involuntary oversight

A major screwup for which nobody is willing to accept the blame. The error isn't important enought to the person who made the mistake to acknowledge; however, the victim of the error suffers greatly. A meaningless apology may be offered. A prime example of Doublespeak.

"We will add your pay raise beginning next week. The paperwork was mismanaged. We apologize for this involuntary oversight.
