shinty-six 

A number. More specifically, an unfathomably large number expected to be expressed in the upper double to lower triple digits in the decimal notation (think, umpteen multiplied by ten). Should generally be the result of adding six to a multiple of ten, but that is not required.

"I only have shinty-six days left to live." (Numberwang)
"I drink roughly shinty-six cups of coffee each day." (you've been wondering how much coffee this person drinks, because they're always shaking and their handwriting sucks.)
