The latest invention catering to Generation Slut, Bang With Friends, is now the subject of a lawsuit from Zynga. The company claims its trademark on the "With Friends" thing has been infringed upon, and that the new Grindr-ish app for whorish twentysomethings is a case of "illegal free riding on recognized and valuable intellectual property rights."

The guys who made up the app, purportedly "three twenty-something men over the course of a night and with the help of 'a lot of Red Bull and vodka,'" probably wouldn't deny that they were piggybacking on the notoriety of Zynga's "With Friends" family of apps, which includes Words With Friends, Scramble With Friends, Hanging With Friends, Chess With Friends, and Matching With Friends. Basically it uses your Facebook friend-base to find possible hookups, which would be the exact opposite of Grindr's more anonymous structure, but who needs to be anonymous when you have all given each other chlamydia and made sex tapes before your 21st birthday? (Really, we are not prudes, we swear.)

As Courthouse News reports, Apple already booted the app out of the app store, and Zynga is now seeking an injunction and punitive damages for trademark violations and unfair competition.

Word of advice: Everyone downloading Bang With Friends right now should also download the companion app, STD Triage.
