These are a few expressions which (imo) are overused and if I never heard them again, it would be okay (I’m guilty of using a couple of these, but I’m trying to stop.):
Good to go
It’s all good
You go, girl
Typing “lol” at the end of sentences. Lame way of saying “what I just said is funny, so I'm laughing and you should too”.
Rock star (c’mon, I know a rock star when I see one, and the person you’re talking about is no rock star)
Basically………
The bottom line
My bad
That’s how I/we roll
Making bad choices
In a better place
WhatEVER (if said in a snarky, dismissive tone)
