Heavy Fucking Object

A large metallic object that is not necessarily good at its intended use but makes a great destruction tool due to its immense mass.

Guy 1: How is that new Carpenter's tool you just bought?
Guy 2: It's just a glorified HFO... Although it worked great when I was tearing down a wall last week.

acronym for "Holy Fucking Oshawa"

Oshawa is an extremely dirty place, and it is fucked beyond saving. To truly understand this descriptor you need to live in Oshawa for about 3 months, only then will you have experienced what HFO really is.

But once you understand, you will come to find that there is a little bit of Oshawa in every town, and it is ok to call that little bit HFO.
HateCrime: Hey Showtoons, how was the date last night with Chanelle?
Showtoons: It went alright, I guess. She could some KD up for me, sucked my penis, cried about her kids, smoked a bong, sucked my penis and then did a line before i dropped her back off at the shelter.
HateCrime: Dude, you can really tell that the second kid is on the way. How is she?
Showtoons: 17.
HateCrime: HFO.
