curteousy flush 

When a dump of such great mass is taken, it must be flushed in two or more segments. The first of these flushes is referred to as the curteousy flush.

"Dude you clogged my toilet? Not cool, amigo!"
"Man, you've got some weak plumbing, I gave that shit a curteousy flush and it still couldn't handle me."

Curtesy Flush 

During the process of a large bowel movement, a "Curtesy Flush" is an extra flush of the toilet to ensure no clogging of the toilet.

Maya was having a large bowel movement after eating authentic Mexican food that required a "Curtesy Flush".
