Betty Bailer bails again...
Dustin is such a Betty Bailer.
Betty Bailers often conveniently forget how to use their phones when they're expected at a social gathering.
This is bothering me more than it should - like I knew he was a Betty Bailer but what the fuck. It's not as if I bought the tickets without telling him.

a Betty that has an elevated appreciation for music and enjoys standing/sitting/positioning herself close to sound systems at live shows, not as a groupie for the band or artist, but rather to take in the total music experience.

To be Bettyed is to be at a party minding your business when an ex rolls up on you uninvited just because they know you’re there.
This definition comes from the Taylor Swift song ‘Betty’. The song depicts a boy (James) showing up to Betty’s party as a surprise to get back together with her. This definition can be used in either a positive or negative manner and they party can be either someone else’s or your own.

Augustine: You just got Bettyed.
Betty: what?
Augustine: Your ex James wasn’t invited to this party but he came anyways just to see you.
