Another website that gives a listing of words used by IITKGP students is supported by IIT Foundation and hoisted here. The content mentioned is vulgar as well as vague (very few explanations included), and can best be described as a word-list. I purposely chose to ignore many words from this owing to their vulgarity as well as obsoleteness in today's language.
A well-compiled link of slangs in IIT Bombay can be found on IITBHF and IITBAA's site. An MA thesis on IIT Madras slangs is also reported. Indiatimes also has a compilation of IIT slangs.
Tell me if you have any more links to similar websites and I will include them in this list.
