When you think of hip-hop, you think of cruising in your car, dancing in the club, making it rain and maybe laughing at your grandma ironically busting a move at your cousin's wedding. What you don't think of is a parasite invading your brain with the sole intent to destroy your attention span.

That's exactly what happens when a popular lyric embeds itself in your mind. Anytime someone happens to say the first part in everyday coversation, you can't help but rap the second part in your head. For example, you're in class and the teacher says, "First things first..." You don't hear anything else because you're busy rapping, "I'm the realest (realest)," from Iggy Azalia's "Fancy." If you listen to a bunch of hip-hop, you'll be amazed at how many phrases that popular songs have ruined for you. We've listed 21 lyrical earwigs that make us start spitting under our breath. See if they do the same for you and let us know in the comments below.
