I'm fascinated by slang terms and in many cases one word could mean different things

5. The obvious one is having a good time or having a jol of a time

4. It could also refer to a nightclub or a party i.e we going to the jol

3. Jol could mean to dance - He can jol lekker

2. It could refer to someone being unfaithful i.e He's jolling behind your back

1. This my personal favourite. When you're not in a serious relationship just fooling around then you'll say, we not speening, we just jolling
