raggen

Verb

 * 1)  to move back and forth repeatedly wildly; to wipe, swing or brush wildly
 * 2)  to drive recklessly and aggressively

Etymology
At least since 1649, raggen has been used as a name for the devil, the evil one. This is based on an Old Swedish adjective ragher (cowardly, unmanly, bad, heinous), same as Icelandic which also means sexually perverse.

(Any hints on pronunciation? If it is not based on ragg, the emphasis is possibly different, like tomten/tomten.)

Noun

 * 1) the devil
