An event which occurs every summer late June early July when poshingtons gather from around the globe to watch races whilst teenagers have a pissup, resulting in many fights, injuries and alchol being stolen/confiscated. Altogether a good night.
Dude 1: Dude were you at Henley Royal Regatta?
Dude 2: Yeah was getting proper wasted but had my alcohol confiscated.
Dude 1: yeah that posh guy gave me a dirty look.
Dude 2: I know didn't even see any rowing!
