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 REALLY ugly motorcycle that is ridden often, never cleaned, and maintained at the absolute minimum for it to run. Some rat bikes are built from scrap parts (often from 4 or 5 different motorcycle brands), others start off as nice bikes and gradually become rats. They are often spray-painted camo or matte black to cover all the rust.

A motorcycle bought for less than $1000, repaired and kept in what resembles working order with whatever parts will work, and painted (if ever) with a black rattlecan.
