Also abreviated D.I.T.C. it is a term used to describe when DJ's or producers skim through record shops to find rare vinyls to create a break to incorporate in their music. The records are usually kept in milk crates so that is where the crates aspect comes from. This is also a group formed by Fat Joe, along with Showbiz and A.G., Big L (RIP), Buckwild, Diamond D, Lord Finesse, and O.C.
Eh Yo check this out its that nig from the D.I.T.C. group and he's Diggin' in the Crates at the record shop.
