If you go to study Engineering at Univerisyt XYZ and your friend starts to also study engineering at the same University. Then you inspire your friend to follow you, not copy you.
However, if you took your field studies project on analysing SpaceX's re-usable rocket-launchers. And then your friend also chooses 'SpaceX' as his field study project, then that qualitifes as 'copy-cat'.
But wait! Lets assume, you submitted your report and your friend got a copy of it and a week later submitted your report with the names only changed. Then that is called 'plagiarisms'.
Puntland is guilty of both 'copy' and 'plagiarism'.
