Hi,

The following is part of video on "Thanksgiving dinner etiquette".

Be careful when you plunk that bottle of bourbon down on the table because everybody knows that when the booze comes out, so do the skeletons in the closet.

What does the underlined mean exactly?

I'd appreciate your help.

 

When you heave a rock up into the air so it falls straight down into a pond, it goes "plunk".
I think it gets the name by way of onomatopoeia.
Any behavior that emulates this is also called a "plunk".

So then, if you were to set a bottle of bourbon down on the table with a sort of finality that says "here I am, drink me" then that can rightly be described as a "plunk".

 

WR dictionary: plunk: verb 2 chiefly N. Amer. set down heavily or abruptly.

 

Thank you papakapp and Copyright for the answers.

 

From the same dictionary, in BE we say plonk, not plunk.

Not to be confused with "plonk," as a noun: inexpensive wine. That term comes from soldiers' mispronunciation of "blanc" while in France, I believe during World War I though perhaps earlier.
