look up any word, like the eiffel tower:
The degree of inaccurate portrayal in the attractiveness of a woman by pictures of them posted online, typically by the said woman or her friends on sites like facebook. Due to the hotness distortion coefficient, a picture could be an inaccurate gauge of how hot a woman is if you have never met the woman in question irl. The decimal approximation for the value of the HDC is ±1.273
Hotness distortion coefficient(face+tits+ass+overall body shape-fat)/5
=predicted attractiveness based on picture

*all values (eg face, tits, etc.) are taken out of the classic scale of 10
