Chill is a word that can be used for many things. It could describe being cool and a go with the flow person. Or a cold object. But overall chill is a cool word.

A rush of ecstasy or euphoria that normally climbs from the base of the spine up across the shoulders, neck, head and arms. The phrase is often used interchangeably with "goosebumps", "ASMR", and "tingles". Though ASMR categorizes the feeling by using mostly only textile triggers(such as playing with the hair or ears), there are many other different "triggers" for getting the feeling. In Hinduism, it is known as Kundalini energy. Some people also believe the Holy Spirit, from Christianity, is a symbol for the feeling, and that it, in itself, is the act or 'reward" of worship. It is also known as "frisson". The idea is now well known throughout most of the new world, but only until recently has it come under the microscope.
