Direct translation: to bake your balls/testicles

Relaxing and idling, for example, sun bathing.

“I’m so swak luigat ballas bak hondsleg right now.”

A term used extensively in the SADF was ‘ballas bak’ literally to bake ones testicles in the sun when you have nothing to do. pic.twitter.com/SKcFoblIUx
