A neurological condition whereby the patient's real personality is suddenly revealed by their simple loss of ability to accept views different to their own, Leave or Remain, to the point at which they suspend all respect for others and then enter into raised levels of judgement and hatred creating social division.

Signs include excess heat, hot sunken eyes, redness, finger poking, increased volume, pronounced veins, general appearance of shitty indignation and judgemental and personal posting on social media including memes that are borderline legal.

Brexititis can be highly contagious in closed circles such as pubs, market stalls, farms, small businesses, school staff rooms and hospitals and is more prevalent among people aged 30+. Bed rest is the only cure - hence young people tend never to catch it in the first place.

British slang for "Coitus Interruptus"

Typically used to describe a situation where a British man, after negotiating sexual intercourse with a European prostitute, decides to withdraw his penis, citing the rules to enter her vagina as "too bureaucratic" as well as to prevent the influx of "illegal irritants" like African herpes and Middle Eastern Gonorrhea. More often than not, the word had negative connotations, ranging from fear and loathing to downright impotence.

A "hard" brexit is a violent brexit undertaken with a stubbornly erect penis under the influence of electile dysfunctional pills like Mayagra, leading to vaginal tearing and penile fracture. A hard brexit is usually followed by several years of masturbation and self-flagellation to calm the penis down and in the worst possible scenario, total vaginal reconstruction surgery.
