the chair is full

[Skrej]

I'm never setting next to any of you.

Note to self: Inquire about screen names before inquiring about chairs.

I thought only Americans said 'setting' instead of 'sitting', but my neighbour (from Yorkshire) says it too.

 

[Skrej]

set as in setting my butt,body, etc.

Implied object, I guess.

 

[MikeNewYork]

I have rarely heard "setting" for sitting.

 

[Tdol]

Do people use I was sat instead of I was sitting in AmE? It is fairly common in BrE.

 

[MikeNewYork]

Not very common. You will hear "I was sat" when somebody else seats someone.

As Tdol said, we use "I was sat" for both meanings.

I was sat in the cinema when, suddenly, the ceiling caved in.
I wasn't sure where my seat was but there was an usher nearby so I asked her for help. She obliged and I was sat near a very tall, blonde lady.

Note that in the second example, I would actually use "I was seated".
