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!"

1. noun. It is the sudden feeling of an inexplicable joy one gets when something romantic or idealistic occurs.

When kilig, one may experience the following:

*butterflies in one's stomach
*heart melting
*shivers down one's spine
*irrepressible noises from one's mouth
*uncontrollable smiling
*an inner conflict between hope of something wished for and reality

Kilig may also be defined as that mountain top, floating, on cloud nine, invincible, i-could-keep-smiling, heart aching goodness and feeling which overpowers the mind's ability to think straight, act straight, breathe properly and articulate thoughts into a single comprehensible sentence.
