Heek (fan term)

From MYSTlore

Heek is a combination of the D'ni word "Heek" (short for Ahyoheek) and the English word "heck". This word is often used by fans in environments where stronger swear words can not be used.

Example: What the heek was that?!

Uru Obsession's Ahyoheek tournament is called "What the heek?!".
