A boss head is the reference given to a considerably large spliff. Often characterised by its formidable appearance, a boss head is considered the ideal joint for any occasion.

Ways of spotting a boss head:

- The spliff has a very tapered design with one end measuring 1cm or more in diameter
- The person smoking it appears to be in a blissful place
- (or depending on the user) The person smoking it appears to have had enough and is eager to pass the spliff to the next person
