When one is 90% sure they are going to fart but there is an outside chance they may shart, so just to be safe they seek out the nearest toilet.
If you'll excuse a moment, I have to go make a safety-shart. I don't want a repeat of what happened last week when I shat my britches.

When one is unsure whether or not they are defecating or being fartaceous. Poot-sharting can be a somewhat scary experience for those poot-sharting. Poot-sharting is also very rarely used with correct verb conjugation and is often purposefully used in defiance of English grammar.
“Uhhhh… Jombly… I uhhh…. I poot-sharting!”
“Ah man. I poot-sharting again.”
“I forgot to poot-sharted today.”
“Ah man. I poot-sharting again.”
“I forgot to poot-sharted today.”

When a band does a cover of a previously great song. But does it so terribly that it ruins the old version.
I used to love Metallica's song "One", but since Korn did a cover of it, I can't listen to it without practically crying. A prime example of Cover Shart.
