A 9/11 is a sex act in which a man violently and unexpectedly inserts his penis into the anus of his sex partner. This may occur during or outside consensual intercourse.
When I asked Maria why she broke up with Stanley, she said that he gave her a 9/11 after a night of drinking.

When Al Qaeda terrorist bastards hijacked planes and crashed them into the Twin Towers, the Pentagon, and nearly the White Whouse. Over 2,000 innocent Americans died that day.
Remember 9/11.

The day in 2001 that a major tourist attraction in New York City suddenly became a major terrorist attraction, which later became a major tourist attraction. Washington, DC, was also affected by this phenomenon, but to a lesser extent.
Look at all the hucksters at the 9/11 Museum. Disgraceful.
