SB is
short for Shit Bloke. You
may use this term when one of your mates is being a "Shit Bloke".
To be called an SB you might have done the following:
- Not turning up to your mates birthday dinner because you're a whipped
cunt
- Taking a girl off one of your mates
- Doing a dog act thing to one of your mates
- Not shouting your mates
Or anything that you consider to be an SB act!
