Donald Trump used a vulgarity to describe Hillary Clinton's loss to President Obama in 2008 Democratic presidential nomination as follows:
Even a race to Obama, she was gonna beat Obama. I don't know who would be worse, I don't know, how could it be worse? But she was going to beat -- she was favored to win -- and she got schlonged, she lost, I mean she lost," Trump said, using a vulgar Yiddish word for a man's penis.

According to Oxford Online Dictionary the word schlong means as a noun:
A man’s penis.
There is neither a definition as a verb nor its verbal usage.
According to Online Etymology Dictionary:
"penis," 1969, from Yiddish shlang, literally "snake." Compare schmuck. As a verb, "to have sex with," by 2005. Related: Schlonged; schlonging.
It does have a verbal usage, but strangely it says it started to be used in 1969. The linked Ngram Viewer seems to support it.
What is its etymology? How did it get its traction? Is the word shlong or sclung related with it?
How vulgar is this word? When a word like f-word is spoken, it gets automatically bleeped, but it didn't when it was spoken by him.
