TI

The act getting busted by the ATF for buying illegal machine guns and silencers either by
(1) Doing it yourself
(2) Hiring a bodyguard to do it for you - all because you are a convicted felon who cannot own guns.

Puff Nappy's eyes got REAL BIG when he was suddenly "TI'ed" as he took possession of those illegal machine guns he purchased to take back to da hood.
