Seating disorder 

Common in restaurants - you can't get out because they're perched on the edge with the seat too far back as a result.

Usually affects women.

"Dude I can't get out, her chair's too far out"
"Yeah, she's got a serious seating disorder."

seining out 

Could mean either just giving up, slowly getting out or getting away with something, relaxing drinking milk and water and watching a lot of Seinfeld, or seeing way too many actual signs.

I'm seining out! I'm seeing way to many signs!

Toilet Seating

A phrase used for the act of relieving oneself while sitting on the spread apart lap of another individual while they, too, are relieving themselves on the toilet. The latter individual is then considered the 'toilet seat'. This is typically done in the woman on top position.

My boyfriend and I had to use the bathroom at the same time and couldn't hold it, so we ended up toilet seating.
