Another slang term for Toronto (as opposed to T-dot).
Toronto = T.O. = T-Dot-o-Dot.
See? It pronounces all four characters in T.O.
1. To make sure something
2. To be real on something
"I cross my t's and dot my i's yeah I'm for real" (taken from Post Malone and Kehlani "Feel" lyrics)
Tennessee Department Of Transportation
“I was stuck in a traffic jam in Nashville and there where alot of T-dot cars”
