US Marine and Navy slang for Marine Corps Air Ground Combat Center - Twentynine Palms, California. It's called Twentynine stumps because it's in the middle of the damn desert and there ain't a fucking palm to be found.
"Dude, their sending me to Twentynine stumps right out of Corps School so's I can be a pecker checker to a bunch of jarheads!"
"Drink lots of water, shipmate."
