Anal Wink

Yeah, that's right, you heard me: anal wink. Y'know, I'm tryin' to run a respectable blog here, but then a buncha troublemakers have to go and start talking about anal wink in the comments.

Well, if you insist. Anal wink (a.k.a. the anocutaneous reflex) is the contraction of the external anal sphincter in response to perineal stimulation. Eliciting it can be a useful diagnostic strategy for certain neurological evaluations. (At least, that's what trained healthcare professionals use it for. What you use it for is entirely up to you.) Do not confuse it with rectal tone.

Bottom line: it's a legitimate medical term, really. (Get it? "Bottom" line!)
