Up 1 by Rico.tadow June 3, 2022
An unit stands for 'ugly presentation'. When someone is an Universal Pollution for you, his works would be an ugly presentation. Kindly reminder that Up-1 is (something) per ugly presentation, but does not actually mean Universal Pollution.
Mr. Pollution you still do not hand in your maths homework.

1. To own someone in something they're good at.

2. Also an item in most video games that gives you an extra life, so when you die, you can continue your game.
1. Josh went up to Jon and challenged him on Guitar Hero 2, Josh won. "Oooh! He just 1-up'd you!"

2. "Grab the 1-up! You only have 1 life left."

1-up Girl 

A female partner, however aromantic, wants to have a special connection with someone else. (Take for example the poem "Falling in Like" by Big Poppa E.) A term originating from the first sung Mario song "Jump up, Superstar".
She's nice, however she has Asperger's, she can't really love that much, so she's my 1-up Girl.

1. An extra life(or extra man) that you need in order to progress through a video game. In fact, you'll need enough of these to make considerable progress. Especially if you suck at the game. 1-ups are usually risky and difficult to obtain as items.
2. Also can be another term for sexual intercourse. Shortened form of "1 dick up (one's) pussy or ass."
Damn, Mark sure has a such a quick reaction time and alot of luck to beat Mario Bros on his first time playing it. He beat the whole game singlehandedly without relying on any 1-ups he earned! Mario surely must be happily spending all those 1-ups on Princess Toadstool in bed at this time!

OR

Damn, Mark really sucks at Mario Bros! He can't even get past the first level no matter how many attempts and always uses up his 1-ups! Mario must surely be getting all his 1-ups back indabutt from Bowser in his dungeon at this time!
