The Infraction: Sigh. Back in March, celebrity groupie Kat Stacks put the Young Money "roommates," as she called them, on blast for seeking her out on Twitter. To prove it, she put screen grabs of a bunch of private DMs (that's direct messages, for those still holding out on Twitter) she'd received from them (as well as text messages and emails) up on the Internet. This should go without saying, 'Ye—but Twitter is not eHarmony or Match.com.
Lesson Learned: Don't use Twitter to holla at females. Because screen grabs are a real bitch to explain! Just ask the YM boys.
