Chocoholic: that would be someone who is addicted to chocohol, would it? Whatever that may be...
Also 'attendee'. A <verb>ee should be the object of the verb, not the subject, e.g. payee, employee. 'Attender' would be much better, as would escaper instead of escapee, although the latter is somehow less annoying. Perhaps that's because it's been around longer. I know, I know, it's a living language. Even OED, sadly, has 'attendee'. Does anyone else dislike the word?
