A 'yarn forward' stitch. While you normally hold the yarn behind the needles, for this stitch you will want to bring the yarn forward through the needles (similar to when you purl).
the knitting stitch yf means yarn forward. take your yarn in front of the needle so that it wraps when you knit the stitch. it will imcrease by one and create a hole.

Actually, what you've described is a YO or yarn over. yf just puts the yarn in front for the next stitch, yo wraps it around the needle to increase by one and create a hole that is often used in lace designs. add a comment
