A technique used in programming where not so experienced programmers in a certain programming language, copy programming code to own program and modify accordingly without understanding too much how copied code works. Frequent use of copy & paste functions in an programming development environment will likely name someone as a copypastologist. This terms is frequently used for programmers that are either too fresh (inexperienced) or old (experienced in legacy programming languages and which try to deal in an youngster programming environment).
My friend, how is now 40 is a doctor in copypastology. So easily it can use other programmers code and make it work in own environment.
