Piru (spirit)

A piru is a fiend or demon in Finnish mythology.

[1] However, piru lost its original meaning and refers to only demon in Finnish mythology.

[1] In folklore, a piru is often featured as a nasty spirit of the forest with which a smart aleck either wins or loses a battle of wits, giving or receiving a forfeit in return.

[citation needed] "Piru" is also a mild swearword in Finnish.
