IBTC

an acronym for the "Itty Bitty Titty Committee"

a term to collectively celebrate women and non-binary people with small chests (aka AA, A, & B cups) in an unapologetic, proud way

The IBTC is redefining body standards because they're loud and proud about their small boobs.

IBM

The company forced out of its own PC market by shitty computer manufacturers like Packard Bell and eMachines that made copies of IBM computers and undercut them.

Nobody ever got fired for buying IBM.
