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!

Get the Henley Royal Regatta mug.
Code used by closeted gay men to communicate their intent on attending a gay sex orgy;

Sharpen= lubricate

Battle Oar= one's penis

Regatta= public place, usually a highway rest stop or secluded park bench, where homosexual men go to have unprotected sex with multiple anonymous partners
Mike: Hey Dave, what are you up to tonight?

Dave: I'm so stressed. I'm ready to sharpen the battle oar for the regatta. (wink)

Mike: Sounds good. I'll see you there. (gently taps foot)
