1. a graphic description of an extreme wipeout in surfing, where
the surfer is pinned to the bottom by the force of the wave, and the resultant tension on his leash keeps
the surfboard perfectly vertical protruding halfway out of the water; appearing to spectators on the shore as a tombstone marking a
watery grave.
2. metaphorically, experiencing helplessness in the face of an overwhelming oppositional force, often mother nature.
"Dude, Mark got worked at Waiamea yesterday, he was fully tombstoning!"
Q- "Another beer

A- "
No thanks man - I'm still tombstoning from last night."
