9/11 

Forget the fucking terrorist attacks! Setember 11 is my birthday, and I'll be damned that little thing gets in the way of my time of the year. Quit the mourning and celebrate me you fuckers!

Do you really think I give a shit about a city that lost only about .00017 of its total population?

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.

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.
