Jeff [ing]

A verb, created by the students in the Faculty of Architecture, referring to a professor, student or other member of the Faculty, who is willing and able to criticize your work, give you pointers and at times make you want to cry because your project needs to be completely re-done. It is named after a legendary professor, Jeffrey Garcia, who was known for the "restart-your-project-in-the-last-week" method of teaching. We love him though.

Hey, (insert name), can you Jeff my work, please?
Jeff ingis super needed at this moment.
