look up any word, like hipster:
 
1.
the act of waiting until the last possible second to actually pack when leaving for a business trip, vacation or moving. Even though everyday for weeks you say you don't plan to go out because you need to pack, and you end up showing up anyway.
Lauren: I can't go out tonight because I HAVE to pack my stuff for my trip to Hawaii...
Joe: You can always pack tomorrow.
Lauren: No I need to get it done now.

-Later that Evening-

Joe: What are you doing here? I thought it you HAD to pack tonight.
Lauren: What can I say, I'm a packcrastinator.
