I get why crazy could be bad, but like debetesse, I have trouble thinking of alternatives, especially when you are saying things like "crazy in love" or "crazy busy".
I also keep thinking of all the songs I love that feature the the word crazy prominently.
Also the plan with the hippos is a very silly plan.
I have been writing "craxy" thinking that makes it OK but it bugs me when Dan Savage uses "leotarded" as a cutesy alternative to "retarded" so now I'm not so sure.
Whacky comes from british slang and probably refers to someone who has been hit on the head a lot.
(It's spelt 'wacky'. Don't know the etymology.)
Wordnik says "Variant of whacky, probably from the phrase out of whack; see whack". However, etymology of whacky as imitative doesn't clear up "out of whack" very well.
I do use "ridiculous" a lot anyway, so I've tried using it more when it fits. I've found that "super" also works, but "super busy" doesn't really convey the same hecticness that "crazy busy" does. And I can't really find a good substitute in phrases like "I told you that I'm crazy for these cupcakes, cousin."
I think the popular usage of "crazy" and its ilk carries connotations that synonyms like "ridiculous" and "absurd" don't. And I really can't fault people for using the word as it is defined in the dictionary. Of course, I understand that some of those connotations are negative for a certain portion of the population.
Is it bad when something on Better Off Ted exactly reflects something that's going on in my workplace?
