A phrase used to punctuate a comment or insult. Often misspelled "you're y4", "Your T4", and/or "Your t4". Also the basis for the sorority your-a t-a four-a AND the IOS (Institute of Spazzology). Only seven people, to this day, know the true meaning of your t4.
"What'd you do with the air horn, biznatch...your t4."
