I’ve run across knurd as the opposite of drunk (thanks pTerry). Nevaeh has become a girls name. Words created by spelling another word backwards are semordnilaps (palindrome backwards). Yes, backwards word/names are most often used as character/fictional town/product/company names. (Yob is an exception.) But doof would be so obviously useful. I’m surprised that it’s never caught on.
Do you have a semordnilap that you think should be in use?
When I say, “Yllaria, you’re a doofus,” that’s the same as saying “Yllaria, you’re a shithead,” except I can say the former but not the latter outside of the Pit.
Edit: obviously, I’m trying to be funny, and not actually calling Yllaria backwards food.
Doof would be more apt if feces came out of one’s mouth, but the transition to poop (usually) takes a unidirectional course.
Not to shoot down another great Doper idea, but “doof” also makes me think of Tim Conway.
Or you could call food tihs or parc and drinks eep or eniru. You could call your mouth your elohssa.
I guess it doesn’t happen because it is kind of trams?
Dog–God.
Just sayin’
trams of course being Swedish for nonsense.
If smut is pornographic material, shouldn’t uplifting material be called TUMS?
But I thought porn was up lifting to certain body parts. :o
But after the porn you get a noitcere.
I find the premise of this thread doof. 
The premise of this thread is very definitely doof. 
Ouch, I had not thought of that. Doof would certainly weaponize doofus.
Nice.
So it’s not smart backwards? Or is it?
“Flog” could be used as a euphemism for “golf”. 
If you drink Evian backwards, does that make you naive?
If *doof *became a euphemism for shit, then *tihs *would become a euphemism for food.
If you’re willing to pay lots of money for extra yummy water, you’re naive.
on the other hand, if “poop” spelled backwards is “poop,” then why don’t we call food “poop?”
Yes, “drow”. A much easier to remember term than “semordnilap”.
Saw this years ago, don’t know why it didn’t catch on given its simplicity.
olleh
It makes more sense, too. A word spelled backwards isn’t really an anti-palindrome.
How drol.
Because it’s extremely rare for a word to be coined out of wordplay, and any examples of it are relatively recent.
People were using “food” (including variations) before they were literate; by the time they could read and reverse the letters, there already was a term for excrement, so no one saw any reason to coin a new term.
