Pumpkin Spice anything
Coffee in general
Plus, salt and vinegar crisps, curry, cheese, bacon and wine 
Reality tv - especially those awful ones like Love Island, towie and the all the ones on mtv, whose 'stars' then proceed to appear on all the shows they possibly can, including each others, and having numerous relationships with other reality 'stars,' and so become d-list (or z-list) celebrities.
In a similar vein, the Kardashians, and the Jenners, Hadids etc
X-factor, it used to be alright but it's become a joke now
Sam Smith, and to a lesser extent, Ed Sheeran and Adele (think they're quite funny/down to earth in the interviews I've seen of them, but Sam just rubs me the wrong way for some reason- not sure why?)
I also don't really get the hype around Ellie Goulding and former girls aloud singer and x-factor judge Cheryl (Tweedy? Cole? F-V? Not sure how you spell it! Also not sure what her surname is these days 
)
Make-up trends e.g. contouring, and highlighting - if it makes you feel good then great, but I don't understand it and couldn't be bothered spending my time doing it every day. Also there are some strange ones that I hope don't take off- it seems that wavy eyebrows are a bit of a thing online now.
The Beatles, Michael Jackson, some of the other big acts from the last century - maybe because I'm just too young to understand the cultural impact they had at the time.
50 shades of grey
Golf- especially watching it
Graham Norton red chair stories segment.
Dominos pizza
sushi (and most seafood actually)
Baths, plus bath bombs and body butter, face masks, cleansers, moisturisers etc esp ones that will apparently magically solve all your skin problems
Nights out - lots of noise and alcohol isn't really my thing
hot weather, I much prefer winter as it's the right weather for hot chocolate, boots, scarfs, staying indoors, and wearing one of the many, many jumpers I've got 
snapchat
and yy to subway sandwiches and robert pattison also
However, I love Harry Potter and want to visit Rome someday
