It's a term used when working in the field. When the job is getting tough you have to get back up, dust yourself off, fire up a joint and keep working.
i.e. Joint Up, Spark up a J, Smoke em if you've got em.
In example when Land Surveying: The Party Chief might say, "Let's all j up in the low ground and get this job finished!" or "It's time to J Up!"
