Till This Day! 

A phrase used when emphasising that your still doing something from long ago or something is still being done from a long time ago.

Used and popularised by the american boxer Deontey Wilder in the famous Till This Day! interview, which turned into a popular meme.

Has to be overemphasised in a slightly angry tone when saying it.

emily: Are you still eating that pizza from a week ago?

Sam: Till This Day!

give it up for day 15 

A quote from an episode of Spongebob where the krusty krab stays open for 24 hours. Not knowing how to properly run a 24 Hour restaurant, Mr. Krabs forces him employees and himself to stay awake for days on end, without even allowing them a weekend off. Eventually, they make it to 15 days, and to celebrate, Mr. Krabs rings a bell and shouts GIVE IT UP FOR DAY 15!!!

Adam: Hey, it's October 15!
John: *rings bell* GIVE IT UP FOR DAY 15!!!!

National Rape Day 

Rape day is bullshit, there’s no such thing. If you think you can go around traumatizing people, YOU ARE SORELY MISTAKEN.

Jake: Oh yeah bro, It’s National Rape Day I’m gonna go rape Emily today, can’t wait to traumatize her.

Emily: Hold my pepper spray.

THATS NOT OKAY. CONSENT IS NEEDED

Rainy Day Syndrome 

Often abbreviated to RDS.
Rainy Day Syndrome is the instance where one has exhausted the supply of fun within one's household and begins to feel compelled to venture outdoors.

Guy: "Let's see....I've been on the PC and have been on various websites and contracted various viruses....I've tried to breed the cat and the dog....and I've experimented on hobos...I think I'll go outside".

Hobo: "Thanks to that kid's Rainy Day Syndrome, I now have 8 fingers on each hand and a rather large phallus protruding from my spinal cord".
