Ash pants 

The extreme version of "Liar liar pants on fire". When someone has no credibility left because they've told so many lies. A person with ash pants has had them "on fire" so many times that their credibility has been metaphorically turned to ash, and nothing they say can be relied on.

"Jason said he's definitely coming."

"Don't believe anything Jason says. He's got ash pants."
