frothing
When an algorithm or method creates millions of tiny temporary objects. They overwhelmn the garbage collection system. You may discover this is happening when you profile to find out why your program is grinding along with frequent gc.

One classic frothing example is:

// Get color of one point.
// A side effect is internally creating an object for the pixel,
// which when you do that repeatedly, causes frothing.
 int rgb = bufferedImage.getRGB( x, y );
