Backsnack

When you are eating ass from the back and you get the entire area of skin between the pussy and ass in your mouth. Just a little snack from the back boys!

When I saw her bend over naked all I could imagine was how her backsnack taste.

blackstacking

Adding a large number of African Americans to a group - so that they will give you the outcome that you desire - knowing that they will band together based on skin colors (racism)

"I cannot believe all of the blackstacking by CBS on Big Brother 23! They certainly rigged it so that a African-American would win. Then CBS tried it again on Survivor 41!"

backteck

Biometric physical data has become increasingly important in our modern age. Of course, biological AND behavioral data IS USED CURRENTLY to identify an INDIVIDUAL PERSON. The most accurate is DNA data, however that has nothing to do with the common usage of biometric data. The current most important physical biometric recognition constraints are for computers using FACIAL recognition and FINGERPRINT recognition. These can be used in real-time to locate persons of interest, unique individuals, etc. (An example would be the Boston Marathon Bombing, where the police officials had access to all the closed circuit camera footage on every street camera, and USED FACIAL RECOGNITION, to locate the suspects). There are of many other forms of physical recognition, including: Ear Acoustic, Finger Vein, Footprint, Hand, Iris, Body Odor, Palm Print, Palm Vein, Retinal, Skin Reflection, and Thermography Recognition.
Now, with the advances in Artificial Intelligence (AI), we HAVE to include back technology (backteck), and allow computers to immediately analyze the still physical picture and the physical motion characteristics of an individual´s back hair, as an ADDITIONAL BIOMETRIC measure of a unique individual to AUGMENT the current use of physical biological FACIAL biometrics in such settings. Using AI, this would be an EASY UPGRADE and ENHANCEMENT to the speed of identification, and accuracy for any computer system to biometrically IDENTIFY a UNIQUE INDIVIDUAL.

The suspect almost got away, but the BackTeck recognized them on the traffic cameras, and they were identified immediately.
