What is the word you stutter on the most?

What is the word you stutter on the most? For me it's Sausage rolls, so i like Sausage rolls and here in UK i use to buy them from a bakery called Greggs, it was a nightmare, i ended having to say Hausage rolls so i wouldn't stutter, i would say it fast so they don't notice lol. 2 others I'm worse with are Year and Cousin.
