jump the shart
Knowing that a baby's diaper only has a small poop in it, that there will be more.
Usage: "I won't change your diaper yet, because I don't want to jump the shart."

It's like jumping the shark but worse. Not only does the show now suck but it's sticky and smells like shit. Not to mention it ruined a pair of good shorts.
Diff'rent Strokes was great until they introduced that annoying little redheaded kid. Now that show is shit - it defintely "jumped the shart".
Jumped the Shart
Jumping the Shark is when a show reaches its creative peak. However, jumping the shart is when a show already jumped the shark, and somehow gets even shittier than it already has.
Family Guy jumped the shark long ago back in Season 3, then jumped the shart in season 5.
