When you're in class, just sitting down going about your business, and all of a sudden, you hear another student's cellphone go off. You suddenly check your phone to make sure it's on silent or vibrate, knowing that the teacher/professor has a no cellphone policy. Your phone was on the whole time! You've just been saved by the sacrifice ringtone.
Christina's cellphone: "I WHIP MY HAIR BACK AND FORTH I WHIP MY HAIR BACK AND FORTH"
LaRon: "Oh shit lemme make sure my phone off!"
Christina: "damn why I had to be the sacrifice ringtone?"
