Lots to list but this is all I can think of right now
-people who drag their feet, walk pigeon toed or duck footed
-text measaging, fucking just call someone
-cellphones in general and peoples reliance on them, house phones are just fine
-when people say "that's jokes" insted of "that's funny"
-people who don't understnd when to use "your" and "you're"
-when I'm on the streetcar/bus/train and there's a free seat beside me and another one row infront of me and someone I don't know chooses to sit next to me when I've got my backpack on that seat
-the current popular uses for the words win, fail, epic and true
-family guy and it's horribly constructed plots
