There's a reason why they don't translate the bottom part. It's been discussed before, so you can either lurk moar or wait for someone else to explain it. It's a Japanese word game that's based on syllables, and it would make no sense if they used the word's English meaning. It's the same one they played in the last episode of PlanetES
The TL note under normal circumstances would be stupid, but they do it for all of the words/phrases in the game.
