Robsteners or Robsten shippers are always (huge) Kristen Stewart fans and Twihards! They're interested in the (supposed) love life of two people (Kstew and Rpattz) they’ve never met. They think they’re “meant to be” but are pulled apart or told to keep their love hidden by secret unseen forces aka the big bad movie studio who they’ve turned into the villian along with the media, their management, paparazzi, Nikki Reed, Emilie De Ravin, Ashley Greene, Camilla Belle, Tomstu, ...... and anyone who opposes their opinion. They can't separate reality from fantasy! They are crazy and obsessed!
Robsten fans are crazy and obsessed!
