speaking people in South Africa
, like myself, use it as "gesellig". With a softer 's' sound.
Used in the same context and with the same meaning as gezellig.
"Ons kuier nou lekker gesellig."
"We are enjoying each other's company" (and the current mood)
Also linked with a desire not to part, or otherwise interrupt the conversation and atmosphere.
Really effective if used by somebody holding a cup of coffee.
