Red Sea Wee

When a stray pubic hair crosses over a man’s urethra causing the stream of urine that's coming out to be divided in two.

The name originates from the parting of the Red Sea in the Bible.

Wife: Why is there piss all over the bathroom floor?
Husband: Sorry Love, It seems I had a Red Sea Wee.
Wife: Yeah, well get moppin’ Moses.
