That tagline "You don't get to 500 million friends without making a few enemies" is especially fitting in this exclusive clip new from 'The Social Network,' in which Erica Albright ('Girl With the Dragon Tattoo' star Rooney Mara) gives Facebook founder Mark Zuckerberg (Jesse Eisenberg) a piece of her mind after reading nasty comments Mark wrote about her on the Internet. Among the damage: snide remarks about her bra size and family name, as well as flat-out calling her a, well, not-so-nice word.

Check out the clip after the jump, then be sure to see 'The Social Network' when it hits theaters this Friday, Oct. 1.
