The acronym DILLIGAF expands to: Do I Look Like I Give A Fart ?.
The acronym is commonly used when some asks a pointless or futile question regarding the state of the firewall cluster ? Or they want to let you know that your Checkpoint firewall has, unsurprisingly, crashed yet again ? Or do you care that your MPLS Service Provider just promised guaranteed bandwidth ? Or perhaps, your manager has committed to a “five nine uptime” on five year old assets that have grumpy little gnomes who come out at night to keep them working.
An all purpose statement of deprecation, that works in most circumstances where a weary cynicism is your only defense.
You may wish to consider stronger language, but I do not recommend it.
