The sign for CLINKER involves a dominant S-hand tapping repeatedly on a non-dominant open B-hand. This differs from signs like WORK/JOB, which typically uses two S-hands or a dominant S-hand striking the non-dominant wrist or forearm with a downward motion. While a general HIT sign might also involve a dominant S-hand striking a non-dominant hand, CLINKER's movement is a specific, firm repeated tapping on an open palm, distinct from a single forceful blow
