Heyhoo expression to react to something or someone that is not a big of a deal is gone.
As used in this GTA V text
(Trevor used to sell weapons to Wei Cheng then Franklin bombs Wei Cheng's car making him death, Franklin told that to Trevor)
Trevor replied: We won't have anyone to sell super-weapons to but hey hoo!

Get the hey hoo mug.
Def. An expression derived from that look you get when you see your mom having a vaginal discharge...hey hoo....lol
Mom: (moaning, sticking dildo up here cunt) oh yeah, oh yeah, (and yes the climatic vaginal discharge emerges like 4th of july fireworks on a moonlit night)
Boy: (walks in on mom having vaginal discharge) Hey mom - Hey Hoo!
Get the hey hoo mug.
