Check Steam

Check steam is a joke in the *geometry dash* community about the update to the game named "2.2," which is a big update. People would say check steam to make people think it is out, although it has not been out for 7 years, and just released a couple days ago. Therefore, the joke is irrelevant.

"bro check steam its out"

"dude check steam"

"CHECK STEAM OMG"

foot check

When you squat down in a public bathroom so you can check that gap under the door for feet, to learn whether or not a certain stall is empty

I wasn't sure whether the stall was occupied, so I casually performed a foot check.
