An iPhone application to promote Pepsi’s Amp Energy drink is creating a stir on Twitter, where users have labeled it sexist. The app is meant to help men with dating and suggests pickup lines for 24 types of women, putting them into categories with names like “nerd,” “cougar,” and “treehugger.” “Our app tried 2 show the humorous lengths guys go 2 pick up women,” the company posted to its Twitter account. “We apologise if it’s in bad taste & appreciate your feedback.” A spokesperson for the company said it is considering pulling the app, but hasn’t made a final decision.
