How to Customize the Shape of Your Bokeh in Photos and Videos

Get some stiff black paper/posterboard, cut out circles the size of your lens diameter (leaving a tab with which to hold/remove the cutouts), and use scissors or an X-ACTO knife to cut out your desired shapes. Hold the paper in front of a lens with a large aperture (i.e. any fast prime). That's it! There are also some more tips below for properly centering the shapes.
