trouth trach

A very dumb misspelling of something along the lines of "dumpster diving" but with trash instead. Trash trounce maybe, I don't know. You most likely looked this up after watching a Papa Meat video titled "The Man Who Cooks His Diapers" and the subtitle at 4:09 made you think something along the lines of "Oh my god, is this some horrible word like munting turned into some funny meme?"
Or maybe that was just me.

Papa Meat: What the fuck is "trouth trach"?
Subtitle: You don't wanna know.
