Heydan

An extremely annoying female human idiot. Typically raised in a rural area at a small private school. Having the street smarts of a wild cat in NYC and the academic smarts of a typical 8th grader. Very annoying around people she knows and she doesn't know her "friends" hate her.

God Amanda is such a heydan whenever someone says a word that sounds like penis she passes out laughing.

Hayday

Something people say to feel like they've matured and grown when they truly have not.

Person 1: Back in our hayday we didn't get this much homework.
Person 2: You fool, what hayday? We always got this much work!
Person 1: Oh yeah. What's wrong with me?
Person 2: My thoughts exactly.
Person 3: Did someone say hayday? I was quite the baller in mine.
Person 1: Go away dude.
Person 2: Yeah nobody asked you!
