As we’ve already established, PopWatch generally approves of Janet Jackson’s comeback single “Feedback.”

However, Christine Fenno just pointed out that the song does include one of the most unfortunate lyrics of Ms. Jackson’s career: “Cause my swag is serious/Something heavy like a first-day period.”

(Pause for chuckling/gagging. Insert your own “Miss Jackson if you’re nasty” joke here.)

Is this, as our headline suggests, the worst lyric in recent memory? Or, can you quote another line that tops it? Oh yeah, we totally dare you.
