rakish

I'm a little stuck... Click here to teach me more about this clue!

'jaunty' is the definition.
(I know that jaunty can be written as rakish)

I can't explain the remainder of the clue.

Can you help me to learn more?

(Other definitions for rakish that I've seen before include "Jaunty; fast-looking (boat)" , "Marked by unconventionality or disreputableness" , "Profligate" , "Dapper" , "Dashing and slightly disreputable" .)

I've seen this clue in the Sydney Morning Herald.
