It is when a male is too scared to try
something or doesn't want to complete a simple task because he may
get into trouble.
also can be used as an insult when
you know that you can kick the other male's ass if he attacked you.
"Hey Albert! Go ring that person's
doorbell and run."
"No guys i dont
want to."
"Dude...Stop being such a school-boy bitch"
"Oh Carl? He's just a school-boy bitch. I can kick
his ass."
