The Imperial version of a small measurement, The expression is used when something is nearly there and lined up and it needs that "Poofteenth" more ! American cars when being worked on usually need the bolts tightened a "Poofteenth" more to get them done up. Asian cars that use the metric system need their bolts tightened up by a "Millifluff".
"Hey Cletus is that transmission back on the truck yet ?" "Not yet Bob I jist haft tighten this bolt a Poofteenth an it's done ! "
