The Entire Row in Front of Me

There are some people, ever crazy.
At least it seems, for it is quite hazy.
The first one is of course the weirdest.
The only guy, who "passes" every test.
The second one, a definite screamer.
Who'd beat every person with their femur.
The third of course is much of a talker.
I'm pretty sure she'd have a bunch of stalkers.
The last of course is the looniest of the bunch
To what she does I have no hunch.
To her, all I can say is, "Sah!
남자야?"
