I've had the message below by email. The term '86' isn't used in the UK so I'm hoping you US folk (call out the Yobs) can confirm the meaning.
Start of email message..........
You have the origin of this famous phrase correct but way off in its meaning. I was born in NY and my Grandfather has told me more than a few stories about Chumley's Bar. During proabition, Chumley's had several
secret hide-a-ways and secret exits including one to an alley off 86th street. This was a quick exit if they were raided. Hence the term "eighty six the joint"
This term means to slip away or to leave quickly.
