A expressive dismay over a tv show/film/magazine article/music/the hairstyle you've ended up with after paying for and etc.
The saying that what you've experienced yourself through,heard of or from is a load of rubbish, shit, poo, garbage (again etc).
To shorten or euphemise the term further would be to say it as a "Hunka Junk".
The recently released movie with the stereotyped gun's and blood criminals along with the hero saving the victim from peril is a "hunk of junk".
The "hunk of junk" that tv broadcasts in the present day would even shame the inventor.
Our vechile sure is a "hunk of junk" and I am not saying that as it being scrap metal.
