Shiba or shibas means thing or things. The more common use is two or three shibas (
shiba, shiba, shiba..), which means, shut up, or just a
dismissive be quiet,
that's enough. (depending on the tone of voice you say it in.)
"That's a big
pile of
shiba."
"Wow look at all the little shibas!"
Said to someone who is annoying you, "Oh, shiba, shiba, shiba!"
*usually followed with
a wave of your hand in the direction of their face.
