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!"

Overnight Emails 

The emails you find in your in box that get sent to you when every one you know is asleep. These will include offers of generic Viagra, penis enlargement, unique but unspecified business opportunities, lotto or prize draw win notification and of course the classic 'help me share my $5million' offer from a man who may or may not have been high up in the Nigerian Finance Minestry.

Tim started each day at the office, mucking out his overnight emails. How he wished he hadn't filled in his email address on the site that offered cheap Viagra.
