A high school in Delaware where the kids spend their free time having sex with each other, smoking pot, and pretending that they have the best band in Delaware when actually, the band sucks. They only have a large mass where they quite obviously believe that quantity is better than quality. They wish their band was as cool as the Cab Calloway Spirit Marching Band's and they can't even compare when it came to the 2009 Brandywine indoor competition when they were obnoxiously overpowering. Suck on That :)
Girl 1: Here comes AI DuPont's marching band!
Girl 2: Lets leave. Cab already wiped the floor with them.

Verb. To engage in the act of smoking cannabis.

The term stems from the announcement that cannabis advocates will be distributing 4,200 free joints in the District of Columbia's DuPont Circle neighborhood on January 20, 2017 to peacefully protest the anti-cannabis positions of President Donald J. Trump, Vice President Michael R. Pence, and Attorney General Jefferson B. Sessions.

January 20, 2017 marks the date of the 58th Presidential Inauguration at which Donald J. Trump will be inaugurated 45th President of the United States.
Do you feel like going to DuPont and picking up some Totino Pizza Rolls before we watch President Trump deliver his inaugural address?

A school in Delaware full of pot smokers, wannabe gangsters from Hockessin and Charter rejects, AI students think they are the best at everything, especially band. But in reality, the school they think they are better than, The Charter School of Wilmington (the nerd school of the state) beats them repeatedly in just about everything ranging from academics to athletics every year.
Student A: "Hey, did you get into Charter?"
Student B: "No, I guess I have to go to AI Dupont."

Catching fish by lighting a stick of dynamite and throwing it as far as you can into a lake or river, and then netting all the fish stunned by the explosion. Considered by most anglers to be excessive, it can be time saving if you have a large fish fry to prepare for. It can also lead to late-night visits from the BATFE and/or the Department of Homeland Security.

Named for the DuPont Company, who have been manufacturing explosives in the United States since the early 19th Century.
"Hey, how're we going to get enough fish for tomorrow night?"

"Grab the DuPont fishing lures and meet me at the lake; I'll show you."
