I

Island
The actual playable area of a dart board (inside the doubles ring). Missing this area entirely is sometimes referred to as "off the island".
Ichigo-byo
In Japanese it means "Strawberry Disease" but taken apart it, the word strawberry: "ichigo" can mean 1 (ichi) and 5(go). Japanese players use this term for when they aim at 20 but hit a 5 and a 1 along with the intended 20. It is equivalent to the English term breakfast.
Irish Ton
Two single 1s and a triple 1; ie: it would be worth 100 if it were five 20s instead of five 1s.
