The act of removing a cunt from your
facebook account.
People often go through their friend list periodically, removing people that they no longer have contact with. However, decunting is only done when a particular friend's updates and self-promotions become so
annoying that you can no longer stand hearing about them. Decunting may take place after realising that a particular Facebook friend is
homophobic, sexist or racist, judging by an offensive status they have just posted.
This is an example of decunting:
Status update: "James
Brown hates fags". "James Brown loves Tony Abbott". "James Brown says "
Australia, love it or leave it". "James Brown hates boat people".
I better decunt my
Facebook by removing James Brown as my friend. I never realised what a horrible cunt he was until now.
