Euphemism used to discreetly express that one is under the influence of Adderall.
Person A: I just spent six hours making anagrams out of my sister's name, before which I cleaned her entire kitchen with a toothpick and inventoried all my possessions with color-coded markers and 2x2 index cards that I cut myself at 3am while you were sleeping!

Person B: Sounds like somebody has been cruising down Highway 80.

Get the highway 80 mug.
A driver, usually from Forney Texas, who exits highway 80 to drive on the service road in an attempt to avoid traffic. Sometimes they will drive the service road on the westbound side, go under the bridge, then back to the eastbound side. This is because a narcissist is all about him/herself and believes that do not have to wait in traffic like everyone else.
Joe:

Damn! Look at that Highway 80 Narcissist go! He really thinks he doesn’t have to wait like the rest of us.

Jim:

I see him! He probably beats his wife also!
