Get squished at the bottom of the screen
Chances are that this will be your every first trophy that you earn. All that you have to do to meet the requirements is to get "squished", die basically. To get squished at the bottom of the screen, move the acceleration button (, ), and position your ship at the bottom of the screen; then hold down the boost button () and crash into a narrow corner. You will blow up and the trophy will unlock. You can also do this in areas where you need to teleport through an object.
