Definitions by USAFA guy
IHTFP
Acronym that originated in the 1950's at MIT meaning "I Hate This Fucking Place". Adopted by attendees of numerous schools afterwards; most notably by the three US service academies, where the letters find their way into not only conversation, but a great deal of graffiti-like uses and spirit missions, or both. Most cadets/midshipmen tend to believe their school (West Point, Annapolis, or USAFA) was the one to originate the term.
