Kyaa 

Not actually a word. It's the sound of a girl screaming.

You want an example? Put a fake spider in your sister's bed.

Bee Yan'kyaa 

This term is considered derogatory in areas pertaining to South London, as it describes one (generally one of Nigerian descent) as being a victim, slave or (in some cases) a dog to the ever-mighty Henri Jeanson. The troglodyte in question has been known to indulge Roblox minors, take bummy subjects and generally exudes large amounts of unemployment.

This bum will, however, exhibit subservience to his superiors, notably Henri Jeanson.

Person 1: Hey look at Henri Jeanson walking his dog!
Person 2: Ah, that must be Bee Yan'kyaa.
