Beautiful

Back in the 1980’s it was common to use beautiful sarcastically to insult someone for having a nasty/cruel personality.

The key to saying it correctly in this instance is the level of sarcasm you use.

Ex: You’re beautiful.

Ex2: Lord, that bitch is a beautiful piece of work.

Ex3: Go watch the movie Heathers.

Superior

In the 1980’s, the slang was used to say that someone was feeling above everything, or their peers, who they saw as beneath them in some way. It could be used sarcastically as well, but it was mainly used as a way to get their friends to help them to humble themselves in some way.

Ex: I’m feeling a bit superior tonight.

Ex2: I’m just so superior, & I need you to talk me down. Can we go do some dumb shit?
Ex3: Thot thinks she’s so superior. How about we bring her back to reality.
