Part one for epi_lj: something in your environment that gets under your skin or irks you but which you either can't or haven't bothered to do anything about, especially if it's a completely irrational irk over a relatively minor thing
for the anonymous person who wanted something I cooked (for some value of 'cook'): take some leftover pasta and add some parmesan cheese, margarine, and a bit of sour cream...yum!
