The perfect way to describe a mullet thats mostly mullet and almost no bangs. Can be used openly in public, because no one knows what a 10-90 is.
10% bangs, 90% mullet; 10-90
Person 1: HOLY SHIT!!!! Do you see that 10-90?!?!
Person 2: Hell yeah!! There's VERY little business in the front, and one hell of a party in the back....

Someone who grew up primarily in the 1990s, or who has a fanatical attachment to that decade regardless of the fact they were born later. 90s kids and the "things they remember" are a popular subject for irritating Buzzfeed-esque pop culture lists extolling the virtues of that decade.

Dude 1: "Awesome."

When someone (most likely a player in a video game) is doing something extremely fast and not thinking about it at all. It can be the most stupid thing imaginable.
