You probably found this the same way I did, watching season 8 episode 5 of chrisley knows best. I can only assume it has something to do with a penis

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.

Alot of people use the term Trout for a 40+ man out looking to pickup younger girls so maybe it means someone looking for older men? Others think it's being interested in large penises..... the term was mentioned on Chrisley knows best when they were looking up handler names for cb radio.
