What does the small rope mean in Xiantao dialect?

This is usually used by adults for children. For example, when some children especially point out that some girls are more delicate and some behaviors appear to be self-centered, adults will say that grabbing a small rope is not a harsh tone, but it is not a joke. Because most of these words will not be said in person. Ha ha.

Xiantao dialect is extensive and profound, which deserves our in-depth study.
