that sneaky walk you do past the person who caught you red handed. similar to slinking away. Even though you were caught you act like nothing happened. When doing the stealth walk, you lean forward and walk in a way similar to a lizardlike dinosaur.
person 1: Dude, my mom caught me eating a bag of chips so I totally stealth walked past her and she looked at me all weird
Person 2: radical man. I stealth walked out of Costco with a hanful of store d'ovures
