To keep ones options open. Like a bird flying along the coastline, neither heading inland or out to sea, refraining from making a decision at the present time.

Generally refers to a current indecision about where to party that night when given two possible options.

Used most commonly in New Zeland where birds can be seen loitering around the coastline, often a common location for bars/clubs.
"hey where are you heading out tonight? (Insert name here)'s party or clubbing downtown?"

To jump around a lot, keep showing up at different places.

E.g. Never stay in one spot for long.
I.e. Business travelling. Band Touring.

Originally intended for large distances, hence "coast".
But nowadays (with more instant updating and specific geo tagging) not limited to. One might as well be showing up at different places (preferably peripherally opposite) in a city given a delimited time period.

Can be described as a more conscious type of jet lag. You are aware of your body not catching up to acclimatize to the new surroundings.
Seen on George's wall:
"Tuesday: George checked in @New York"
"Wednesday: George checked in @San Francisco"
"Friday: George checked in @Washington"

- Hehe :) travel a lot this week, George?
- Yes, I've been (feeling) a bit by coastal lately ;)
