Coined by the big wall Yosemite climbers of the late 70s and early 80s, a pebble wrestler is a boulderer that appears to be "wrestlingpebbles" from the view from Yosemite's Half Dome or El Capitan.
It is an adjective used to describe someone or something in a very positive way. It can be used in a wide variety of situations but essentially means 'good'.

That was a pebbley goal.
You're a pebbley looking girl

A small, individual, rounded piece of shit not large enough to be a proper turd. These are usually not larger than peanut M&M's.
I felt like I gave birth this morning. I was expecting at least a foot-long slimer, but I looked in the bowl and there, staring back pathetically, was a single, sad pebble turd not even worth flushing.
