1. A vagina rotational movement similar to Helicockter, but in
female version.
It is usually used as counter attack to Helicockter.
When the penis rotates inside the vagina clockwise, the
female counter attacks it by rotating the vagina anti-clockwise, and vice versa, so the penis will twist and bend to
one side and lose its proper functional at the moment. *But in some cases, overly thrust and followed by quick sudden rotational may cause its dysfunctional permanently.
In worst cases, It may cause a broken
bone and/or inability of the males to effect sexual reproduction.
2. A circle-swinging vagina movement that most women do after shower, usually intended to
dry the external and internal area from water to avoid vaginal wet mount (vaginal smear).

Example 3:
