A meaningless phrase, started by a retired Minecraft modder (The founder of the IndustrialCraft mod)
Mostly the word is used as a "filler" word to break silences, as a greeting or a goodbye.

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.

A form of greeting similar to hello and hey, used by only the most enlightened of speakers. Rhymes with Mayo

Hayo is the name of a wonderful, outgoing, smart and cheeky angel! She is wonderfully gorgeous and has the best hair anyone could wish for! She’s a funny, but sometimes annoying in a good way, and amazing friend. A hayo is someone who will make you laugh when there is nothing left in the world. Hayo is someone who will make you annoyed then make you laugh at the same time. Boys secretly admire hayo but none seem to show it. Hayo talks a lot! But that is the reason why she is a good, funny friend and will also give you her honest opinion on everything. Hayo is very truthful and trustworthy. If you ever find a unique girl called hayo, don’t. Let. Her. GO!

if you have a Hayo in your life u are lucky. Hayo is a very funny and warm-hearted person but she also has a temper and trusts me she is not a person you would wanna get in a fight with. Hayo could be your bestie or your worst enemy. She always speaks her mind no matter what. but some times she doesn't have faith in her self and brings herself down instead of raising herself up.
