The beverage company has been running a "Share a Coke" promotion since this summer, swapping in customer's names over the "Coca-Cola" logo.
Part of the marketing plan is a website that lets users customize a virtual Coke can. Although the app blocks explicit words, it allows users to write pretty much whatever they want. Unless they want to write the word "gay" (or "gays").
That brings up an error message: "Oops. Let's pretend you didn't just type that. Please try another name." (Sorry Marcia Gay Harding, Gay Talese and Randall Gay)
"Hetero" and "Straight" are cool though.
