How would you translate:
"She could talk anyone under the table, and she usually did."
Thanks.

I don't even know what that means in English!
Do you mean somebody who is "soulante"? or somebody "qui te prend la tête?"
Sylvain, au secours !

I also don't know the meaning of this in English! So I can't be of any help as it is.

According to Wikipedia (ugh! -- the only place I can find a definition):

to talk somebody under the table =
1. (idiomatic) to bore (somebody) with excessive talk or numerous arguments

My wife said "soulant." Doesn't look like a verb to me...

It seems like this must be a variation of "to drink somebody under the table," to continue to drink long after the other person has given up and gone to sleep or passed out under the table.

You can use "saoulant(e)" or the verb "saouler" (you don't pronounce the first a). Be aware it's familiar form though. By the way, "se saouler" means to get oneself drunk.

What an uncommon idiom. I agree with Chris that it is a variation of to drink someone under the table but I think it has nothing to do with getting drunk.

I am thinking of the English word garrulous to sum up the idiom, but the often offered translation to loquace for French seems inadequate. Bavard would be too light. Does garrulous translate into some form of garruleux directly?
