Upside down Y pose 

A pose men with scrotums do when it is a mild to hot day and it's sweaty in the nether regions, so that, therefore, before and after, they're ballsacks do not stick to their legs

"blimey mate, hot as fuck eh?"
"aye mate, doing the upside down Y pose, my balls sticky"
"mate, shave"
