Library Shorthand?

In honor of David Pogue's great list of possibly new online abbreviations and acronyms I wondered if we can create some library related ones for our teens to use (after all, we introduced YNK to tons of teens who had never heard of it).

How about these:

G2GCTE: Got to Go, Computer Time Expired
CBFTH: Can't Borrow: Fines Too High
GBLC: Great book, Lousy Cover
AARBWD: Any Accelerated Reader Book Will Do or ABAR: Anything But Accelerated Reader

or maybe some to simplify the rules for them:

PUH: Please Use Headphones
GOHL: Get off his/her lap
TYFO: Take Your Food Outside


Can you add to the list?
