The act of taking a drink of hard alcohol the California way, straight from the bottle.
To correctly execute this you must:
1. persuade all of the people around you to pick up a bottle and join in.
2. unite all participating bottles in the air as a toast.
3. shout "cali pull!!!"
Guy 1: Lets take some Cali Pulls before we hit that party!
Guy 2: Great idea!
Together: CALI PULL!!!!!! (clink)
...the next morning
Guy 1: What happened last night?
