Boston Shuffle 

When someone wipes their arse with the same piece of toilet paper in a back and forth motion, rather than the wipe once and drop method. It’s not clear why people do this, but it probably smears shit all over their backside.

“There’s a strange sound coming from that cubicle, like someone sanding a piece of wood”
“Oh that’s probably Clive, he likes to do the Boston Shuffle. He’s smearing it around like peanut butter”
