between tongue and uvula
The uvular is the dangly bit you can see at the back of your mouth. The sound is made by squeezing air between the back of the tongue against the uvular. This sound is rarely used in beatboxing.
The following diagram shows where the Uvular Fricative is made in the mouth.
This iconophonic isn't currently used in any BZZKTT sound.
