A very distinct type of individual who tends to sit far back on the toilet seat when shitting, often times leaving fecal crumbs on the back of the toilet seat. The SitBacker signature is characterized by a V shaped doo doo crumb pattern, produced by the combination of the squashing of ass cheeks on the toilet seat, and the ass crack.

That part of when you're out eating at a restaruant and you start to feel full, but you aren't completely finished eating. To cure this, you sit back in your chair and wait for a minute or two before you go back to eating.
Ted: *Burrrrp* Man I'm feeling full but I still have half a burger...
Carl: Just do The Sitback, you'll feel better in a minute.
