WalkGood
means: hello, goodbye, wishing a person the very best in their endeavors/journey, to travel with good spirits, peace, love & affection towards others, RESPECT, almost like saying “blessings” even in the face of stressful/traumatic/tense or demanding environments.
in the closing of a letter instead of writing “Sincerely,” you can use “WalkGood,” your name. Or as someone is departing, you say WalkGood my friend.
