Bent out of shape

What is the meaning of the phrase "get bent"?

"Get bent! -- I despise you!" From "Flappers 2 Rappers: American Youth Slang" by Tom Dalzell (Merriam-Webster Inc., Springfield, Mass., 1996).

That's kind of weak, isn't it. "Get bent" means go get a penile injury. Doesn't it fellows?

As a fellow, I agree it's rather flaccid, but how would I know?

Here in the NE part of the US of A I have always used and heard that phrase in two different but related ways.
One way is to use "bent" as a word to mean drunk or high as in "I was so bent last night I don't remember a thing".
Another way "bent" is used is to castigate or criticize someone who makes a dumb remark as in "Whadaya talkin' about, you're nuts, get bent will ya".
Outta here!

I always thought that "Get bent!" arose from the earlier phrase "Don't get all bent outta shape, willya?". Whether either phrase (or both) has anything to penile injury, I have no idea, but it's lamentable how frequently the subject of genitals rears its ugly head.

Head? No pun intended, right? :)

I hadn't heard "Get bent!," but, as an insult, it isn't very plausibly construed as a descendant of "Don't get bent out of shape." The latter means calm down, don't react so angrily/bitterly/haughtily/whatever. "Get bent," if derived from that, would be a command to get mad.
