What Do Frogs Have to do with Knitting?

I was recently asked by a new knitter about the term “frog” when referring to knitting, or rather unknitting.
When you frog your knitting it means you are taking the needles out and undoing the fabric, you are ripping it out…….”rippit, rippit, rippit”
Another term that may be unfamiliar to new knitters is “tink”. Tink is knit spelt backwards and means to undo your knitting one stitch at a time.
