1. What does it mean?
풀피 combines full with 피, the familiar gaming term for health. It means a character currently has their maximum available health, contrasting with 딸피, having very little left.
Also written or said as pulpi
2. The nuance
Full health does not necessarily mean full mana, armor, or every resource. Figurative use about feeling energetic is playful rather than a statement about actual medical health.
3. Examples
“회복하고 풀피로 다음 구간에 들어갔어.”
I healed and entered the next section at full health.
“풀피였는데 함정 한 번에 체력이 크게 줄었어.”
I had full health, but one trap took away a big chunk.
