##Simply annoying Tweets

Annoyingly extended words (4+ of the same letter in a phrase): `OOOOHHHHMMMMYYYYGGGGOOOODDDD`

    ([a-z])/1{4}

Tweet w/ just a single hashtag: `#omgthissucks`

    ^ *#[^ ]+$

Not a regex, but self retweets: `In case you missed it I pooped this morning :)`

    In case you missed it

##App Location Updates

(updated for multiple words in Location name)
Path app location updates: `(at Location) - path.com/foo`

    \(at [a-zA-z0-9_ ]*\) — http://[^ ]+$

Foursquare app location updates: `w/ @twittername 4sq.com/foo`

    w/ @[^@]+ http://[^ ]+$

More Foursquare app location updates: `w/ 8 others 4sq.com/foo`

    w/ [0-9]+ others http://[^ ]+$

Yet more Foursquare app location updates (seriously...): `(@ Location w/ 4 others) 4sq.com/foo`

    \(@ [a-zA-Z0-9_/ ] w/ [0-9]+ others*\) http://[^ ]+$
