vs this guy (or anyone really) c/c turn is horrible, you have to lead or c/r big but most likely c/r - this guy sucks, get money in the pot asap!

As played I mash the call button as hard as I can, he's waaaay more likely to have a 9 or 5 or two random cards he felt like bluffing with than a set/overpair. It's useless assigning ranges to someone this loose but just know that he most likely has random crap easily enough of the time to call this.
