It is a word used to refer to anything that lacks substance.

Had a long time crush on Petita Mwanza. While ku fest I bumped into her ku VIP( Yes,I had a VIP ticket) 😂😂😂 I told her with my chest njebele “Hi!!Can I just get a hug chaku mutima chichoke??” Okay the wines gave me courage. All I’m trying to say is don’t be a kembo.
