Elbow noodle

Miss Veda Pierce, an inmate at California's Folsom Prison serving time for killing her mother’s estranged husband in 1945 when he refused to become her lover, writes:

Dear Grammer Genious,

What is an elbow noodle?

Signed Veda Pierce, Prisoner #14858

Dear Veda,

You must be pretty much out of it from spending so many years in the slammer. It’s a very popular fad expression among the young people nowadays. An elbow noodle is when you’re standing next to somebody and you tickle them in the ribs with your elbow. Like in, “I think he likes me. He gave me an elbow noodle while we were standing in line.”

Hey, do you prisoners still bang on your tin trays to piss off the bulls? Just curious. I just watched Wallace Beery in "The Big House" again.
