stat check 

It means that in a fight even if you play it perfectly but have a lower number the higher number will win and not the higher skill, doesn't matter if you play well, dodge every ability, you will lose if you have the lower number.

Jax: *kills Vayne even if she played it perfectly*

Vayne: "lol i lost a stat check"

Jax: "ez noob"

Calling "seatcheck" is alot like calling out "shotgun" in the fact that it is used to claim your: chair, sofa spot, futon, stair, whatever your seat may be, when you want to get up for a moment. It lets everyone around know that that spot, while vacant, is still occupied.

"Man, I'm thirsty. Seatcheck!"
