A close call. Going to the absolute final brink of a terrible situation and coming through unscathed.

Derived from having to take a powerful shit and squeezing the cheeks of your ass together in order to waddle to the toilet, making it just in time and releasing the vice grip on your anus to birth a fecal fist, likely to produce a splashback that is as refreshing to your anus as the new found relief of your large intestine.
Person 1: Holy shit, you almost hit that car!

Person 2: Yeah, I totally buttcheeksed it.
