To laugh in Laura-esque style. Generally performed in online encounters. Some would suggest the laugh is sarcastic, however critics suggest it is used as a deterrent to un-intelligent beings.
It is widely accepted as being Laura's signature laugh and to perform it without permission is unwise.
To make the noise one must whisper the "kiki" really quickly.
Rumours have it that it has Japanese origins.
Person: What's that mean?
Laura: It's my laugh!
