The result of spending large amounts of time in the library before a deadline or exam. Lack of exercise and constant snacking on biscuits results in a notable increase in body mass especially around the waist.
"All those biscuits have given me a serious case of library belly that I need to work off before the holiday."
A sexually frustrated woman who converts bottled up sexual energy into energy spent turning the library into a mini dictatorship. She will badger library goers with pedantic and pointless rules such as, "No sitting on the tables" and "No loud talking". To sum up, library nazis are generally undesirable women with large ghetto asses.
