Fantastic Fourgy 

When there is a tight group of friends consisting of 2 guys and 2 girls who would probably end up having a foursome. Differing from the Fantastic 4 because there are 2 girls instead of 1, and 2 guys instead of 3. Standard foursome rules apply:

1: Guys can't make eye contact

2: Guys can't make bodily contact
*Exception*: High fives are acceptable

Person 1: "They're always together, I bet they're a Fantastic Fourgy"

Person 2: "We should form our own Fantastic Fourgy, and fight crime and stuff"

Fantastic To The Fourth Degree

This expression is used whenever something so fantastic occurs, or you receive news of such a fantastical nature, that you have to describe it with a positive adjective such as, "Fantastic" - alongside the words, "to the fourth degree." By using this expression, you are emphasizing the sheer awesomeness of whatever it is you are describing. This expression can be used when you find out you are going to be a mother/father! You can also use it when describing your last coitus session.

Person 1: So dude, how was it banging that girl we met last night??
Person 2: Dude, I have never had an orgasm of such a magnitude. It was fantastic to the fourth degree.
Person 1: Marry her.
