People across North America, including in Canada, New England, Southern California, and Virginia, call mixing all fountain soda flavors together a "Sui/cide".This term is most common among kids at self-serve dispensers in restaurants, skating rinks, and fast-food chains. You will also hear other names for this drink, depending on the region:
Graveyard: Popular in Texas, New Mexico, and the Pacific Northwest.
Swamp Water: Often used in parts of the Midwest and New England.
Kamikaze: More common on the West Coast.
This is what Google had to say on the subject. I think I got it from my grandmother who used to live in Virginia, because I've never heard Graveyard and I've always lived in Texas. I use the term Swamp Water oddly enough for a mix of two parts Sprite to one part blue Powerade and one part orange Fanta, because it turns green, but I came up with that myself. Kamikaze coming from the west coast makes sense though. I've never been over there, but my grandfather did man a gun at Pearl Harbor.
