The act of transfering an arbitrary amount of bodily excrement between two consenting parties, done so by the following series of precise maneuvers.
Party A first kneels on the ground, and bends his/her head over to touch the floor so that their asshole is facing straight up, preferably stretched open.
Party B then sits on top of Party A, such that the assholes of both parties involved are directly aligned. At this point, either or both parties proceed to defocate into each other, the idea being that the fecal "data" is "transfered" from one body to the other, as would actual computer data.
1. Erin wants to please Ben on his birthday, however she is currently on her period. Instead of sex, however, she decides to open a data transfer between her and Dan, so that Ben can watch until he is satisfied.
2. When Stuarts mother found large smears of warm brown shit all over his bedsheets, she realized that her son in fact was into data transfers, just as she and her husband had suspected.
Data lake, is commonly used for describing a large-scale tool where multiple data sources from different types of systems are fed in and parsed in pre-defined methods.
However, it is also quite common to see where incompetent peeps use when they do not understand a dime about data or data-science. Since it is not publicly well studied or understood area, some peeps use this 'term' to fool non-technical executives to extend their own projects.
A: "We will build a massive data lake, analyze everything from all the sensors with AI on the fly, orchestrate all the processes and automate everything and everyone's tasks"
B: Oh, that's nice. So you can hand in your resignation next year after delivering this project.
