Definition - "there is truth in wine"
The classy thing to say when you've had too much to drink and have just said something that is decidedly not classy, in vino veritas has been employed as a mea culpa of sorts for thousands of years. In the first century AD, Pliny the Elder referred to the "common proverb that in wine, there is truth in vino veritas."
First, Bacchus is mery, Wine moderately taken maketh men ioyfull; he is also naked; for, in vino veritas: drunkards tell all, and sometimes more then all.
— Abraham Fraunce, The third part of the Countesse of Pembrokes Yuychurch, 1592
