As for the Bobbitts, that whole situation seemed the butt of jokes, just like Buttafuoco
Those are two humorous and bawdy aprtonyms, or last names that are oddly prophetic. Another one is Anthony Weiner
Less funnily, we also have tennis star Margaret Court, astronaut Sally Ride, footballer Jim Kiick, sprinter Usain Bolt, golfer Tiger Woods, genius Marilyn vos Savant, and former White House press secretary Larry Speakes
I'm not sure if this (or even the Clinton-Lewinsky affair) is the most emblematic moment of the nineties. I would think the fall of the USSR would be more significant, along with the US passage of NAFTA. Ruby Ridge, the Waco Massacre, and the OKC bombing were also key turning points in the 90s which directly connect to the political dissension we're facing now.
Those are all landmark events that characterize the nineties. Domestic terrorism was a thing then and is again today (Jan 6, intimidating school boards and election workers, Q-Anon), but the Clinton impeachment stands out for me as the most important element on your list, and I would add two more (see below).
The Clinton impeachment was the death of forbearance in American politics. This was the rise of Newt Gingrich and the beginning of the death knell for inter-party civility, Forbearance refers to the idea that even though the parties had different ideas of what would lead to a safe, prosperous future for Americans, they were both still trying to accomplish that somewhat cooperatively. The two parties both respected the Constitution, showed one another mutual respect, acknowledged that the other party not only had a right to participate and should be treated as friend and loyal opposition, but played an important role in governance of the nation just as gas and brake, though opposite, are each necessary in concert to successfully move the vehicle forward. Those were the days when unity and bipartisanship were not just possible, but common, and productive.
That's all gone for good now, I believe. Every prominent Democrat since then has been trashed with loathsome character assassination (both Clintons, Gore, Kerry, Daschle, Reed, Obama, Hillary, Pelosi, and now Biden and Harris). Dragging Bill Clinton over the coals for nothing more than being a Democrat was the shot fired across the bow. It was mean-spirited, and the beginning of party over country for the Republicans. When asked why he chose impeachment over censuring for Clinton, Gingrich answered, "Because we can," which will characterize the Republican's approach to the House in the next two years.
Beside the rise of Newt Gingrich and scorched earth American politics, we also saw the politicization of Christianity (Moral Majority, Falwell) and its merger with the Republican party arise in the 90s.
Also, the incessant propaganda. Technically, the advent of hate radio was earlier - Limbaugh premiered in 1988 and became a player about 1989. But think about how these three brought us to today in a way that
Combine the loss of forbearance with nonstop conservative indoctrination media and a theocratic tendency that has led to the modern Supreme Court, and what we see today is explained.
