Don't believe the hype 

Ignore the media, marketing, buzz, or rumors around a story, object or person -- it's nothing special. From the 1988 Public Enemy single "Don't Believe The Hype", which fought back against negative press about the band.

"Is the new Star Wars movie any good?"
"Nah, don't believe the hype"

Don't Hurt 'Em

A warning/compliment issued to somebody that looks so good they risk injuring others just by being seen. It's unclear by what method this injury would occur, but presumably cardiac arrest or colloquial heartbreak. Also, may refer to the pain one feels in his/her gut upon seeing someone extremely attractive. May be described as a punch in the gut. Someone who is hurtin' em may elicit wistful sights of strangers as he/she walks by.

Anna: Did I show you this minnie-dress I just got? : Walks out :
Becky: :Jaw Drop: Damn, girl! Don't hurt 'em!

Don't call me that in public.

The automatic response when somebody says "Jesus Christ!" in exasperation. It implies that the person thinks you are divine compared to their sorry ass. There is also an undercurrent of blatant self-promotion, in that it's fine for them to call you the Lord behind closed doors, but you don't want them embarrassing themselves in public. This usually pisses them off, but it stops them from whining.

It can also be used when someone yells, "Jesus!" "God" or some related phrase.

Does not necessarily need to be used in public.

Mary: "eh my God, it is soooo hot outside. Jesus Christ!"
You: "Don't call me that in public."
Mary: "What?"
You: "You heard me."
Mary: "What?"
You (patronizing): "Shhhh..."
