Short for '''I'''n '''B'''efore '''T'''he '''L'''ock. Somebody on a MessageBoard has made a thread that is just guaranteed to get killed off before it goes anywhere. It's inevitable. So, as a rather thinly-veiled attempt by other uses to boost their {{Post Count}}s, they simply post IBTL in the thread as it comes up. This is often looked upon with the same disdain as contentless UsefulNotes/FirstPost spam, but since most threads that get this treatment are doomed anyway, it's less likely any action will be taken.

If the thread in question gets ''deleted'', then their PostCount spamming is all for naught.
