The "Konami code" is a cheat code originally designed to be used with an NES controller in Konami video games from the mid-1980s. Over the years it's found its way into many other game systems and OSes. It represents the buttons that must be pushed in this order:

Up Up Down Down Left Right Left Right B A

The code usually gives the player a full powerup or extra lives. It's also often called the "Contra code" because that game was considered so difficult that many believed it was impossible to win without using the cheat code.

Dude, if you're having trouble getting past that boss, try uuddlrlrba!

uude 

(n.) short for unnecessary urban dictionary entry.

this may include definitions of friends, widely known celebrity names, entries that should not have been qualified according to entry guidelines but for some reason made it through the system anyways, words that already exist in real dictionaries, and just about every single entry that has ever been included in urbandictionary.com ever, including this one.

urbandictionary.com is full of uudes.

Uudoism 

Supporting a God called Uudo Sepp and greatly admiring not only his singing, but also his skills on piano.

Uudoism is known to be the most common religion in Estonia, especially in Tallinn.
Uudoism has been predicted to be as popular as Christianity and Buddhism by year 2025.

The main idea behind Uudoism is belief in one true God - Uudo Sepp, and following his pure views on life.

Person A: Hey dude, my mother told me to pray at church then I can play Fortnite, wanna join?
Person B: I'm sorry, I can't. I must follow Uudoism and attend to my Lord's "meet&greet.
Person A: Ok... I think I'm not Christian anymore. Let me invite my friends along.

I wouldn't talk to your parents about it unless it's a good time. The relationship seems tricky to navigate. Maybe have a friend or auntie around to intervene in case it gets tense.
