9/11

A synonym for "hahahaha" or "lol". 9/11 = .8181818181, and since "H" is the 8th letter of the alphabet and "A" is the 1st, 9/11 = "hahahahaha".

Bro: Shawn Johnson can be cute sometimes but other times looks like a dude that got his face teabagged 24/7 in the gobi desert.

The 9/11

The 9/11 is a sexual technique performed by 2 men and a woman. The men have to lie down with their penises relatively close to one another so they resemble two towers. Then the woman has to "slam" the towers by inserting them in the vagina and anus or mouth one after the other.

Dude, the 9/11 we pulled last night was so dope. No homo though

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.

9/11

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.
