How do you answer funny when people laugh at your big ass?

The hip is the joint of the waist and legs, and the skeleton is the pelvis composed of two hip bones and sacrum, with gluteus maximus, gluteus medius, gluteus minimus and piriformis attached. Hip shape backward, with iliac crest on the upper edge and gluteal groove on the lower edge. When standing upright, the buttocks are square, and the buttocks on both sides are obvious.

Female buttocks are plump and obese, and the intersection angle of posterior superior iliac crest is 90; Male hips are small, square, angular and obvious. The intersection angle between the posterior superior iliac crest is 60.

The tightness of hip muscles affects the perception of hip position, but does not change the height of hip line.

The height and hip circumference index of women is greater than that of men, because the hip circumference is not warped. Women of the same height have wider hips.

Hip line

The gluteal line, anatomically called gluteal sulcus or gluteal-femoral sulcus, refers to the skin sulcus between the gluteal muscle protuberance and the upper end of the posterior thigh. It's more obvious when standing.

The tightness of hip muscles affects the perception of hip position, but does not change the height of hip line.

Some people's gluteal muscles are tight, others are slack and drooping, which affects the perception of "breech position" because of different muscle shapes, but the shape of gluteal muscles does not change the height of gluteal line.
