Green Lake Itch: Seattle, WA
The rash one gets after swimming in Green Lake, a man-made lake located north of downtown on the other side of Lake Union. "The itch" is relatively harmless, but considering that it is caused by the many ducks and geese (and all that they secrete), it has caused many Seattlelites to swim elsewhere.
Halfmoons: Utica, NY
Cookies that have white frosting and chocolate frosting. In many other places they are called half and half cookies.
