Forked pee
When a man is urinating and interference from the peehole causes the pee to split into two simultaneous streams. It usually occurs after sex or going to the bathroom after getting out of bed in the morning. Depending on the geometry between the two streams, it is possible to get both of them into the toilet bowl. However, it's more common for one to go in the bowl and the other to hit the floor, rim, seat, etc.
Science still can't fully explain the seemingly magical phenomenon known as forked pee.
Fork in the Pee
The moment when a guy starts peeing, two (or more) paths of urine come out of a dude's penis, until finally rejoining into one path as a result of a urine elixer.
Guy: I had to pee so bad, but I had a fork in the pee and went on the floor.
