The ye olde family tradition of visiting various grave sites usually of recently dead family members. In extreme cases, visiting dead family members that have been dead for centuries. Could also mean perusing the headstones of random people and usually involves making fun of their names or the flower selection of the month.
"Oh no not again! Dad, this is the third time this month we've gone headstoning!"

"That cemetery down the road has the greatest opportunity for headstoning with over five acres of prime headstoning real estate!"

"Assden! Makerberry! Yeaste! These names are too funny!"

"These yellow and pink carnations are too gay for an outdoorsman like Peter was."

The headstone handy is when you go to graveyard at anytime and receive a hand job behind a headstone.
Mark- "i just received a headstone handy"

Jack - "what's a headstone handy"

Mark - I'm glad you asked, it's when you receive a hand job behind a headstone in a grave yard"

Jack - "oh cool I can't wait to get one f those"
