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.
