This is an
excuse used by
rock climbers to explain why they did poorly out on the
rock. It is similar to, but more
humorous than
excuses such as "my shoes were
too tight" and "I forgot my
chalk bag."
Examples:
Climber #1: "Dude, why didn't you stick that dyno?"
Climber #2: "High gravity day."
Climber #1: "Man, I've never seen you grease off a nubbin so easily! That thing was a jug!"
Climber #2: "High gravity day."
