Geld weld refers to semen that dries on the tip of one's dick after ejaculation that later causes an erratic stream of urine. Walls, floors, shower curtains, and other unintended targets are often showered in the process. Geld is the German word for money and in this instance refers to a money shot.
In the movie 'Me, Myself, and Irene,' Jim Carrey's character gets a geld weld after a night of sex and hilariously pisses all over the bathroom.
