What the phrase likely means
Quik Head appears to be slang built on “quick head,” a crude term for fast oral sex. When applied to women in their 40s–60s, it reflects a stereotype rather than a reality.

Why the stereotype exists
-
Sexual double standards: Older women are often either desexualized or, conversely, hyper-sexualized in narrow ways.
-
Cultural tropes: Media sometimes portrays mature women as more “experienced” or less constrained by social expectations.
-
Ageist bias: Labeling reduces complex individuals to a single, sexualized trait.
-
Projection and myth-making: People project fantasies onto groups, then treat those projections as truth.
A grounded view
There’s no evidence that women of any age group share a uniform sexual behavior. Preferences vary widely by individual, relationship context, and personal values. Reducing a demographic to a sexual shorthand is more about cultural bias than reality.
