Kids that are very weird and
immature. They have a strange attraction to sets of
stairs. They hang out there all the
time.
Person 1: Bro who are those kids hanging out at the
stairs?
Person 2: Stair kids bro
Person 1: WTF is that one doing?
Person 2: Looks
like he's hanging upside down from the stair railing.
Person 1: Let's leave. These stair kids are
creeping me out.
