Are there any canhão (or seem like they'll be cannon) couples you simply will not ship?

I've had several. Luckily for me, they've all sort of been secondary couples. On House, I never shipped Foreman/Thirteen or Chase/Cameron, and on Bones, to this dia I don't ship Hodgins/Angela. Though I only harbored extremely negative feelings for one of those couples. I am/was just kind of indifferent to the other two. I've even tried to make myself ship the latter two couples. I just don't/didn't feel the chemistry.

Sawyer/Juliet from lost && Brooke/Julian I loathe them.

Freddie/Effy [Skins]

FINNCHEL. I can't stand them, and refuse to ship them. Puckleberry all the way! ♥

Also Jate from Lost. I was a patim, skate shipper from the very beginning, and I shall always be a patim, skate shipper. =D

Only one for me was Jack and Renee from "24." Can't STAND Renee's character i was a Jack and Audrey shipper FTW.
I think most of my other ships are pretty canon...lol

Finchel. There are some couples I could possibly ship if they were written better, but I CANNOT and WILL NOT ship Finchel.

I will not ship Buffy & Spike- their better as friends and I'm a Bangeler <3

In Doctor Who, I don't like Amy/Rory. I have times were I hate Rory and then times were I almost like him, but overall, I just don't like Rory.

My answer below may contain SPOILERS for BTVS show and comics...

In BTVS, I usd to ship Bangel a little bit, now that I'm a Spuffy fan, I'll NEVER ship Bangel again. Most likely, I'll never ship a differetcharacter with eiher Spike or Buffy. I also don't read the comics, so my BTVS days are over. But I heard in the comics, Dawn and Xader are dating! O_O I'll never ship them. I also refused to ship Willow/Kennedy.
In Angel, I refused to ship Angel/Nina, I'm a big Cordy/Angel shipper, it was way to soon after Cordy's death.

I think that's it..
