look up any word, like yeet:
 
1.
An action performed just as you say goodbye to someone. To perform a high five as you leave, rather than greet somebody. Often performed with a loosely held hand and a relaxed air about the gesture.
"It's been a good day. see you later."
"Yeah man, bye."
(Both Bye-Five before departing)
