Thomas Traversa did this nice Wave Grubby during the PWA event in Cabezo (Tenerife) this year. Basically this version is a normal Grubby technique, whereas the “Reverse/Campello” has no air time and is initiated by an active turn. The board stays always on the water. On the other hand the “Hangover” is a Wave Grubby, in the air and off the lip. 

 

Watch the variations of the move:
