TCB

Takin' Care o' Business. As in the BTO (or, rather, Office Depot) song, but it's an old, old phrase. Also the name of Elvis Presley's band ('68 comeback and later) - that band gave Elvis Costello the nucleus for his first post-Attractions venture (King of America): Jerry Scheff, James Burton (once Ricky Nelson's guitarist), and Ron Tutt. Elvis P's notion (IIRC) was that "TCB" meant giving you your money's worth on stage, but it can also be a synonym for "phoning it in".

TCB /T-C-B/ n.

[IBM] 1. Trouble Came Back. An intermittent or difficult-to-reproduce problem that has failed to respond to neglect or shotgun debugging. Compare heisenbug. Not to be confused with: 2. Trusted Computing Base, an `official' jargon term from the Orange Book.

One of the many “TCB” logo items Elvis had custom made were gold necklaces which he gave out as gifts to his friends. The the charm has the initials “TCB” over a lightning bolt. Much cheeper replicas are available for those people who need to have this interesting piece of Elvis memorabilia. One web site offers an 18” replica with rhinestones (on the lightning bolt) for under twenty dollars. For those on a budget there is also the gold tone version for about half the price.
