Top Definition
The name of a disease which occurs due to exposure to excess levels of Twilight hottie Robert Pattinson. Symptoms include writing "Mrs Pattinson" repeatedly on surfaces, referring to Robert as R Pattz, a fetish for vampires and hatred of Bella Swan.
Around 90% of the female population are suffering from Robsession. Don't be next. Try to stay away from gossip magazines/Twilight as much as possible.
