Formerly used as an onomatopoetic expression to describe the sound of laughter in '60s theatrical jargon.

A decade later was used as an expression of distaste, disgust, or revulsion by people who attended comedy clubs, probably due to the disgusting nature of the jokes told in a more vulgarity-tolerant society. Can also be used in its adjective form, yucky.
