Any ads for womens pissy pads that suggest all women, when they hit 50, suddenly piss themselves when they sneeze, cough, hiccup, or fart. So rude!
Omaze ad. The woman's face and voice gives me the rage. 
Obviously Daisy Daisy Daisy Daisy Daisy Daisy Daisy Daisy Daisy fucking bastard Daisy!
Any funeral plan or pension plan ad that's aimed at the over 50s, but features actors over 70 only.
Domino-hoo-hoo. 
The one for Lenor (I think it is,) with the girl with the shaved head snuggling up to her fresh sheets!
Any betting/gambling ad.
Any Just Eat ad (except the Katy Perry one which I quite like.)
Super noodle taste-aaaaaaaaaaaay...
The EE one where the family supposedly landed a plane! (Though I've not seen that in a while.)
Every fucking begging charity ad. 'Will you give just three pounds a month to help?' So SO many ads every fucking day.. How much money do they think we've all got? 
I also loathe the 'every answer is BINGO fuckwittery' on the ad breaks on The Chase!
I am sure there are more!!!
