The main point in the video is that Psy is a rich guy who is a total jerk and you can see the irony in the tittle because he's not a gentleman at all.
The dance that Psy does is called the "Arrogant Dance" which first was introduced by Brown Eyed Girls
Who are the celebrities we see in Gentleman?
Just like Gangnam Style we see a lot of celebrities in this video.
The main girl is Ga-in and she is from Brown Eyed Girls and as I mentioned before that is the group that first introduced the Arrogant Dance.

What are the Korean foods we see in Gentleman?
If you had watched Korean dramas you may notice that the characters always go this kind of food trucks/tents which are called "Po Jang Ma Cha" where they usually buy Soju beer and street food :)
|Food was great!!|
|You can see Soju (green) and Beer (brownish)|
What is that big noodle that Psy is holding and eating? It's a rice cake called Garraetteok and it's used to make another dish called Tteokbokki which you can see in the table with a red/orange sauce
|Psy eating Garraetteok|

Here Psy is eating Udong that is simple hot noodle soup.

Why "Wet Psy"?
|Gonna make you sweat. Gonna make you wet, You know who I am "Wet Psy"|
In the variety show "Infinite Challenge" Psy lifted his arms to reveal his sweaty armpits. And yeah Sweaty armpits = Wet Psy
I have a headache after writing all this haha but it was fun to recognize many things that I watched in Kdramas and personal research :)
I hope you can watch the video again and know some of the things I explained here :)
