What are your biggest pet peeves?

My pet peeves are: a blasting radio/TV and other loud noise, people who pronounce their "c" and "k" words too strong, dirty fingernails, seeing fat people go into fast food places, when people say "birfday" "mouf" "toof" and "skreet" instead of birthday, mouth, tooth and street, snapping on gum, banging the fork against the mouth when eating, smacking, burping or belching out loud to name a few.
