Various drugs can cause it - all very rarely, you are indeed a very special snowflake - but when that's the case, usually your skin is blue too at least somewhere on your body. I haven't heard of laxatives doing it, but it's the kind of thing that happens so seldom and is both embarrassing and obviously not life-threatening, so it might just never have been reported to a drug agency. If it's just the toilet seat but your butt isn't particularly blue, it's probably skin bacteria (and certainly a surgical stay in hospital is a good way to acquire some new ones,) in which case a scrub with chlorhexidine soap (I think Hibiclens is the US brand name?) may stop you from being a blue menace.

How does that even happen?
I know people who would like you to sit on their hair.
