Pepsico has apologised for launching an "offensive" iPhone application which offered tips on how to seduce women and invited men to brag about their conquests.
Customers have threatened to boycott the brand in protest at the Before You Score game.
The App, to promote the AMP energy drink, categorised women into 24 types including such as "sorority girl", "rebound girl" or "married".
Each category came with advice on how to talk to that type of woman, as well as directions to the nearest hotel.
"Get lucky? Add her to your Brag List. You can include a name, date and whatever details you remember," the site advised.
"You got it? Flaunt it. Keep your buddies in the loop on email, Facebook or Twitter."
Popular women's blog, Jezebel, criticised the brand's iPhone service as "completely unacceptable and ridiculously offensive".
The blogger, Hortense, wrote: "This is a program sponsored by a major corporation that encourages men to look at women as objects to be won, used, and tossed away after a 'victory' is obtained, and the more normalized things like this becomes, the worse off we're all going to be."
Before You Score has not been withdrawn but a representative from Pepsi used the AMP Twitter account to say the game was supposed to be funny.
"Our app tried to show the humorous lengths guys go to pick up women. We apologize if it's in bad taste and appreciate your feedback. #pepsifail," they wrote, adding the hashtag critics have been using to discuss the issue on Twitter.
It is the latest example of a social media strategy backfiring on a major brand.
Earlier this year, Habitat apologised after an "overenthusiastic intern" used online search terms about the disputed election in Iran to promote a sale.
