Thanks! I didn't know those two.

Dutch Courage="courage in a glass", or "liquid courage".

Here in West Virginia, we've been known to "red up", meaning to tidy up a little bit, but not actually clean. It's a regional saying, though, and oftern attributed to "burghese", or "Pittsburghese", a dialect originating in Pittsburgh, Pennsylvania...or, if you'd rather, "Pixburg, Pannsavaynia".

Why do dogs lick themselves?   Because they can!

Such Yiddishisms are very common in the US and certain parts of London.

This particular term has several meanings besides the obvious.

Yea, I went to college with a Pittsburgian.  There I learned that "y'all" was "youse guys".  WHen we laughed at that, he said ok, use "yurins".  We asked him to go back to youse guys.

No, I have to correct you here, Doc; the more common usage of the term, in Pixburg, is "yinz guys". "Youse" does occur, but "yinz" is more commonplace.

I think you are right (youse being more Boston).  It was a long time ago, and I try not to visit Pittsburg too often.

Attend to the following sentence:

"Firs, ah'm goin' ta da Strip Distric' t'git sumpin' to eat; then ah'm goan to watch da Stillers play da Brahns on TV. Then ah'm goan dahn-tahn, ta da tiddy bars 'n'at. Enny-a yinz guys wan' go wid me?"

(Translation: "First, I'm going to the Strip District (shopping area) to get somthing to eat; then, I'm going to watch the Steelers play the Browns on TV. Then, I'm going downtown, to the titty bars and that. Any of you want to go with me?")

That is classic "(Pitts)'burghese", for all you neophytes out there.

I find it surprising, but I still could read and understand it!
