LOLOL.....I had to look it up:
Catch Out
1. To get a ride out of town on a freight train.
2. To successfully attain a ride for hitchhiking purposes.
Dirty Kid: Let's jut kick it, right?
Crusty Kid: No way! I'm going to sleep. I gotta catch out in the morning.
Andrew Hippie: How are you getting to Portland?
Kung Fu Kitty: I'm headed down to the 5 right now to catch out!
