"Slime" (スライム or "suraimu") is used as a pun: "suppai-raimu" (スっぱいライム). "Suppai" (here, スっぱい) means "sour" and "raimu" (ライム) is Japanese for "lime". The flavor is actually "sour lime" and not "Slime"—that is, unless DQ Slimes taste like sour limes. Right?
The gum also promises "Slime food feeling", which gets a big nothankyou from me.
