megacrush 

When a girl has a crush on you, but you are too noobish to realize, or you are too shy to do anything about it. This girl will hang out with you and give you all the opportunities in the world for you to make your move, but you never will. This will only inflate the megacrush.

Unfortunately, you will only find out about the megacrush well after the window of opportunity. This information will haunt you for the rest of your days.

1997
Girl: Hey, I just rented Scream, and I'm too scared to watch it by myself. Do you want to come over and watch it with me?
Boy: Nah, Dave and I are gunna go play Mario Kart 64 tonight.
Girl: Oh... ok...

2007
Dave: Hey dude, remember back in high school that girl Kate?

Moron: wtf! She had a crush on me!? I am teh fail!
Dave: Yup.

megacapitalg

MegaCapitalG aka Randall Lee Jordan is well known in the "Second most watched Yugituber in the Western Hemisphere". He is widely known for his memes and being the "scrub" of Yugioh YouTube, having random and overwhelming confusing discussions/ideas on how decks or cards will impact the Yu-Gi-Oh Meta. He's also know for hyping up "underrated" decks in the Yu-Gi-Oh meta.

MegaCapitalG is the second most watch yugituber in the Western Hemisphere but after that cubic I'm not surprised that he's a grown ass man.

megafart 

An extremely powerful act of flatulence. The amount of gas expelled is far above, often several times of normal. It makes a very loud, thunderous sound which can be heard even from great distances. They are known to occur mostly in the early morning, but can strike unexpectedly any hour of the day, depending on diet. They are also odorless or at least don't smell as bad as silent and regular ones, considering most of them comes from swallowed air or hydrogen composed by digesting large amounts of high-in-fibre foods. If you are lactose intolerant, eating dairy products may give you a bad case of mega flatulence.

A bad example on how a megafart looks like in real life:

Mother: Oh my, what was that noise? Did someone move the wardrobe?
Daughter (from the other room): No, mom. I just ate some sweet potatoes and your delicious macaroni with cottage cheese, and so I'm a bit gassy now...
