When 2 or more people join in the act of "scubing" in attempts to find the superior "scuber."
This is done primarily by Scuba diving but other forms may be acceptable.

scub stands for Slight Chuckle Under Breath, I created thid because I never actually Laugh Out Loud ou Laugh My Ass Off, but I do slightly chuckle under my breath, and so does everyone else.

The best way to clean your genitalia. Using soap, you scub the area in a triangular fashion. This technique is usually used as a pre sexual routine.
