My first nomination is...
Michelle - I can't stand pet names. When ever I visited my Aunt she always called me "Poppet" - up until I was 20yo!
So I find Michelle addressing the housemates as "chicken" in conversation belittling and cliched. I guess it's a northern thing, and probably accepted oop north, but for Jamie Oliver types like me it's like someone scraping their finger nails across a blackboard. Besides that, I think Stu needs a rest.
My second nomination is...
Dan - I do like Dan but haven't seen much of him so far, and he comes across a bit dull.
