What is the most annoying thing about your bf/gf?

For a variety of reasons he is now my ex; but the most annoying, disgusting and embarassing thing he did was leaving his dirty false teeth all over the house...anywhere and everywhere. It was always a "pleasant" surprise when company came over and they would discover his dentures covered with loogies and pieces of food stuck to them sitting on the coffee table or atop the microwave, etc. YUCK!!!
