Question: The [ODO](https://en.oxforddictionaries.com/definition/us/bald-faced) has an example sentence:

> 
> I lost track trying to count the sheer bald-faced, brazen, **well-swilled** out-and-out lies being palmed off as fact or being suggested for our consumption as reasonable readings of the text.
> 
> 
> 

It appears *well-swilled* should be synonymous with other adjectives in the lineup, but I can't find this word in dictionaries. Another [example](https://www.christianitytoday.com/ct/1994/december12/4te003.html) I found:

> 
> Our sixteenth-century forebears used adjectives such as "shameless, fat, **well-swilled**, stinking, papistical … ," as historian Timothy George wrote on our May 16 editorial page.
> 
> 
> 

*Swill* means *to drink, wash, rinse*. But what does "well-swilled" mean here? Urban Dictionary has an entry that suggests it means "intoxicated". This definition does not appear to sufficiently fit the above sentences.

Answer: 
If someone swills their drink, they're sloshing it around (often in their own mouth). As gargling is to the throat, swilling is to the mouth. If a lie is "well-swilled", it's been rolled around in the liar's mouth thoroughly before being spat out on you.
I would suggest that "well-swilled" implies "well prepared", "well practiced" or "well used", as in the lies have been used before and roll off the tongue easily.
