hashtagfuckwit

Refers to people who are so fucking narcissistic that they hashtag every element of every selfie/photo/status update they post ANYWHERE. The hashtags are totally pointless, annoying as fuck and make you want to punch a wall.

Sarah: "Just took a pic of this dandelion. Should I put my water bottle in front of it so it looks more natural? And sit them on my book? Then hashtag myself, my website, my unborn children and all my qualities?"
Matt: "no you hashtagfuckwit".
