Definition

A casual affirmation combining 'for sure' with the '-ski' suffix (à la 'bro-ski') to add unnecessary but charming linguistic flair. Essentially 'for sure' with more confidence and fewer brain cells involved in pronunciation.

Example Usage

You coming to the party tonight? Fashoski, I'll be there at nine.
