When you remove someone from your Myspace or Friendster etc list because they tick you off.

Unfriended 

Some shitty horror film that came out in spring of 2015 about a dead chick who kills her friends with computer hacking and supernatural ass-fuckery. Whoever thought this was a compelling plot device should be thrown off the back of a speeding pickup truck and into a river in a body bag, weighed down with cinderblocks.

-Girl: "OMG UNFRIENDED R SOOOO SCURRY"

-Guy: "yeah, right, it was like, bro. Damn."

-Me: "Who thought this was a good idea, that's like two hours of my life I ain't gettin' back."
