LOBsyn
Lack Of Beta Syndrome. This affliction is caused by people who believe they should be in a beta for an up-and-coming product but they were rejected or simply not picked yet. The sufferers often succumb to fits of rage that mainly target people who are already in the beta group. So far there is no prescription on the market for this disease.
