look up any word, like donkey punch:
 
1.
Town/mini-city in Illinois, connected to the northwest side of Chicago. Noted for it's close proximity to O'hare Airport as well as featuring the Allstate Arena (where minor league teams such as the Chicago Wolves American Hockey League team play, as well as hold concerts), Donald E. Stephens Convention Center, and the Rosemont Theater (also a good concert venue).
My house is being fumigated so I'll have to spend the next few days in a hotel in Rosemont.

Ghetto school in PA.
Did you here, Rosemont is undefeated in chess!
