It is well known
that the East Yorkshire coast is home to the fastest eroding cliffs in Europe.
When I was 15, me and a mate were on a bike ride and arrived at the cliff edge east of Hilston. About 6 inches back from the edge of the cliff was a crack where the next bit of cliff waits to fall into the sea. My mate wedged his heel into the crack and shoved hard. This caused a chunk of boulder clay the size of a loaf of bread to tumble down the cliff and thump onto the (empty) beach along with a load of shrapnel that it had gathered up on its way down.
"That was fucking amazing" we implied. So we began our quest to make the county smaller by systematically doing the same for about 200 yards in each direction.
We then came across a section where the crack ran inland a bit so it was maybe 4 feet from the cliff edge. The crack was quite wide at that point and we sat behind it, trying to shove it with our feet. It moved a little bit but wouldn't go.
My mate wandered off and came back with a big stick he'd found up the track.
He wedged in our ad hoc lever and pulled and pushed and wiggled until it loosened. One good push by us both and a chunk of clay the size of a large sofa toppled very slowly and then rolled down the cliff with a rather loud rumbling, gathering up more clay as it went before landing on the beach with an incredible thump.

However, we then heard an "OYY!!" and a hundred yards up the beach there was a man carrying a load of sea-fishing gear, so we decided it best to get on our bikes and fuck right off. Why he shouted, I don't know. It's not like we almost crushed him.

Out of interest, how did you imply the statement, "That was fucking amazing"? I'm guessing some kind of understated Roger Moore-esque raising of a single eyebrow, but I'd like to know for sure.

On a similar note, are you absolutely certain that you heard two exclamation marks after the "OYY"?

The proximity of the cliff-face
creates unusual acoustics.

In the same vein
A good friend and myself used to go bush and find boulders to heave down hills, crashing into all sorts of trees and small rodents.

Great fun I must say.
