It's the most dangerous curse word you can use. It means all these words together, bitch, fuck you, idiot, stfu, stupid, whore, hoe, clown, show off, teacher’s pet, creepy, dumb, ginger, prick, bastard, arse, ass, balls, cunt, shit, dickhead, cocksucker, burden, problem child, snitch etc. Just all the bad word you know. Use this word wisely, this is more than just a word you know. They don't need to be all of them before you can call them "koudo", but they need to be at least two of those things.

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.
