That note above your paddle says スカ, or Suka in English. It's the game's cute little way of telling you this.
It's not the first time I've seen スカ in a video game, either. Here's another example, from the Japanese release Oshiberi (Chatting) Parodius.
You open up a treasure chest at the end of the game, only to find a lit bomb waiting inside. Note the sign he's holding. Now I don't know specifically what スカ means (it's translated to LOSE in the European version of the game), but if I were to take a wild guess, it's a reference to classic cartoons where the lead character gets punked.
You get the idea. I haven't been able to confirm this with the scant amount of research I've done, but I think this is what the Japanese game developers were hoping to bring to mind. If anyone has more information about this, please let me know.
