Some of the things that annoy me I can't even mention here as it might be offensive for some. However:
-people who drive too slow
-people who ride up on your ass causing you to get over into the first lane after which they pass you but then immediately get over right in front of you
-people who walk in the street instead of on the sidewalk
-double parking mo-fos
-cashiers who take their damned good time
-banks in general (what a racket)
-having to take a crap
-having to sleep
-mosquitos, roaches, ants, and other noessential pests
-that pants half off your ass look
-that played out one leg rolled up look
-when something happens in national news and then the local news media comes on with a story about "what if it happened here, are we prepared??"
-those little animated logo things in the corner of your tv screen that advertise some upcoming show or movie
-tv stations that play a movie then before the final credits and music can come on they go to half screen just so they can start blabbing about what's coming on next
-voicemail messages that pop up on your cellphone days after the original message
-finicky self serve checkouts that can't sense when you've placed your scanned item in the bag so you keep hearing "Item removed from bagging area"
-Head On commercials
-telemarketers and unidentified number incoming calls (totally ignore them)
-parents who let their children run wild while tossing in an occasional "stop it now" which little "Johnny" just totally ignores (makes me wanna slap em silly...the parents, not the child.)
