scrub the shrubs

The act of scrubbing your pubic hair (may also include gooch and/or asshole hair) and area around your genitals more vigorously in the shower than you otherwise would, in anticipation for intercourse. This is done in a meticulous manner in order to rid the area of unpleasant odors or residue (ball sweat, asshole lint, swamp ass, gooch grime, anomalies in pubes etc.)
