antivention 

Antonym for intervention. Where an intervention is an attempt by friends and family to convince someone to seek help with a substance abuse problem an antivention is an attempt to convince someone that they are spending too much time and energy on a generally wholesome activity and that it's affecting their drinking.

"Dude, where's Robert?" "He said he had to work." "Again? He never wants to party since he made Assistant Manager. That's it. Get Harold, Kumar, Barry, Landfill and Fink. We're going over to Robert's and having an antivention. Bring beer."

Antiversary 

(n.) The calendar day corresponding to a day in the past when something irretrievably shitty occurred.

Tomorrow is the antiversary of my hound dog's death, and I'd rather drink liquid lye than go to work.
