The automatic reaction my body undergoes whenever I hear Blink-182 or any other worthless trendy band du jour on the radio. To see this reflex in action:
  1. Turn on your favorite local "alternative rock" station. Make sure a musician is in the vicinity.
  2. Wait about 30 seconds
If you heard two or three power chords and some irritating vocals for 2 seconds before the musician launched himself across the room to change the radio station, you've just witnessed the blink reflex.

If the musician's fist has accidentally slammed through the stereo, make him/her buy you a new one.

The blink reflex is what keeps those of us who try to write and play somewhat meaningful music from going crazy due to the sheer idiocy present in the music industry today. It's a good thing.

Do not try to suppress the blink reflex. If you change the station back, you will be spat upon by any musicians in the room.
