Engine Work

The kind of bullshit excuse levied by lazy developers at Jagex LTD when they require *Engine Work* to implement a new feature.

Examples
jagex: "'oi guise we're ganna ship group iron man this year!@"
also jagex: "nah mate, can't do nuffin about that, that's engine work!"

redditor: hey jagex its been 1 year what happened to group ironman?
mod ash: engine work
redditor: well, when is it coming?
mod ash: winter 2017
