"Turt" is a simple dumbed down and more derpy version of turtle. Dunno where the other definitions got their knowledge, but its incorrect, turt = turtle.
A little kid just leaving the toddler stage. They can walk but haven’t mastered it yet. Turt is masculine only, it cannot be used to define a little girl. The feminine version may be submitted if this gets accepted.
That little turt doesn’t have to worry about anything.
That’s one of the most adorable turts I’ve ever seen.
