Dabs or wax is basically just a golden, thick, sticky wax. Kind of resembles honey except it cost 60$ for 1 gram. You break of a little piece, or a big piece, and you heat up the bubbler/rig with a torch until it's red hot. Then you simply place the wax in the red hot bowl and inhale.
Margin Rate. Margin rate has multiple financial meanings. The margin rate is the interest charged by a broker or agent for buying securities on margin (purchasing securities with borrowed money). The margin rate is a fee above and beyond a broker's call rate. A margin rate can vary and is dependent on a margin customer's account balance.
Churn Rate. The rate at which customers terminate their relationships with a company over a given period of time. For example, if five customers in 50 discontinue their cable every month, the churn rate is 5%. The church rate contrasts with the growth rate, which, in this case, is defined as the number of new clients or customers. If a company is to grow, the growth rate must consistently exceed the churn rate.
