Rob Kardashian hauled his ass all the way to Austin, Texas to pick up his stripper girlfriend Blac Chyna after her arrest for public intoxication on Friday ... talked about being "trapped" by a stripper!

Rob jumped in his Bentley and drove 1400 miles south to pick up his lady in some yucky strip mall where they likely had Subway for lunch. And of course Blac had to Snapchat the event with her now-signature four-leaf clover which is believed to represent Rob, whose birthday is on St. Patrick's Day.

Well, we're here waiting for them to return ... see you soon, kids!
