Originally an acronym for "third tier toilet," denoting a college or university ranked at or below the third tier of exclusivity by U.S. News & World Report. The millenial private-SAT-tutor set who coined the term on internet discussion boards (notably Princeton Review) during the late 1990s -- and among whom its use remains largely confined -- considered attending a TTT to be beneath their dignity.
Usage of the noun form soon expanded to include any institution, person, locale, etc. deemed likewise lacking in prestige or desirability, particularly if owing to an association with the lower socioeconomic orders.
Adjective usage ascribes to the object the quality or state of being a TTT.
(n.) Midland County Vocational Academy of Agricultural Arts and Sciences -- that place is a TTT. I heard they don't even require any SAT IIs.
(n.) Walmart and Marquee are rancid TTTs, mostly because their patrons are TTTs.
(adj.) Carrying your shit to work in a Victoria's Secret shopping bag is very TTT; mostly fat hispanic secretaries do it.
