pro-chill 

(Professional Chiller) When a girl does not shower until 7'oclock at night before she goes to the bars. It is the girl who drives a fucking Lexus and does not get fucking dressed. She does not carry a purse. She wears neon colored tights, when she decides to get dressed. She does not wear pants to parties.

I was attracted to her because she was pro-chill.

Pro chiller

Is non judgemental.
Enjoys there own company.
Enjoys the surroundings they happen to be in.

Appreciates comphortable footware.
Is a good listener.
Enjoys a relaxing beverage.
Can talk shit for extended periods of time.
Is comphortable with silence amongst company and alone.
Not terribly concerned with what the time is.
Enjoys snacks.

Chelsea is tottaly a pro chiller. We hung out last night and just looked over her balcony and swapped music. We ate chips.
