Go get 'em tiger! 

An encouragement used in ordinary conversation since the 1960's. Expressing your confidence someone has qualities on par with a jungle cat: stealthy and lethal. "Slugger" was a similar boost that didn't survive modernity, now considered mildly sardonic rather than sincere.

Heard you've an interview in Cupertino this afternoon. Go get 'em tiger!

Go Get Fucked 

This is the little-known twin brother of "Go Fuck Yourself." However, the demand is slightly more humiliating and degrading -- as the prospect of getting fucked by some unknown force in an unknown orifice is much more unsettling than merely fucking yourself, or masturbating.

Can be shortened to GGF for brevity.

Steve: Blake told me you had sex with my sister last night.

Buck: Yeah, well you can tell Blake to go get fucked.

Go Get Your Shinebox 

To put someone back in their place by reminding them of their roots or some former activity. To call someone on a bit of hypocrisy. From the film "Goodfellas" in which Billy Batts intentionally goads Tommy DeVito by derisively reminding him he was a shoeshine boy.

"Ugg, did you see Jeremy is drinking PBR? What a hipster."

"Go get your shinebox, you drank it just last week to get in good with the indie broad."

Go get a gun and shoot yourself. 

Basically, an insult when a friend comes up with a better idea than you will ever ever think of.

Justin: Hmm...I think I'll make a game called Counter-Strike for the computer...

Brian: Really? You should go get a gun and shoot yourself...
