I would rather shoot heroin in my wiener vein than...
Get on a roller coaster.
Spend more than 5 minutes in the company of someone I can't stand.
Shoot heroin into my eyeball.
Note* this is not just a thread for things you hate, but, literally, things you would hate more than shooting heroin into your wiener vein.
Note b* If you are a person of the feminine gland, replace wiener vein with corresponding vein wherein fuzzy biscuit.
