Dude 2: Dude he totally pulled a "Harriet Tubman."
When used in the context of Beirut it is usually used in conjunction with the 50-yard line rule.
It may also be used to describe an escape from a situation requiring you to go underground (literally or figuratively).
"House Rules: both people sink a cup = balls back, ..., 50-yard line, no Harriet Tubman..."
"I built an igloo last week with an underground tunnel, just in case I had to Harriet Tubman that shit if we were attacked."
