This is more an interesting abbreviation, but I hope you will forgive me. BYO is an abbreviation that's been in use for some time, usually seen in restaurants, it stands for 'Bring Your Own', and it usually applies to wine or alcoholic drinks. BYOD means Bring Your Own Device.
(Seemingly more and more companies are asking employees to provide their own electronic devices, at their own cost. This means employees have the freedom to use a device that they prefer over one issued by their employer and employers don't carry the burden of providing computers, smart phones and other mobile devices.
Of course I have no choice but to BMOD.)
