Is there a word for mangled idiom that becomes commonplace - eviltoast

Like “does the Pope shit in the woods?” or “that train has sailed?”

Also, what good examples can you think of?

    I like ‘bob’s your oyster’ because both original phrases are nonsensical to me. Is there a word isometric to portmanteau but for phrases / idioms?
