When kilig, one may experience the following:
*butterflies in one's stomach
*shivers down one's spine
*irrepressible noises from one's mouth
*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.
OR that 'tingly' and 'excited' feeling you feel, especially when watching romantic films.
i don't think there's an English word or phrase for it. even Butterfly Stomach doesn't do justice to "kilig".
i have never met anyone as puzzling and amazing as you.. i am always thinking of you every night before i go to sleep..
Girl: *blushes* thats kilig...
