The Congo has similar girls - and they will do anything to increase the sizes of their backsides - including using bouillon (also called stock) cubes.
How do they do that? They dissolve the cube in a cup of water, then inject that water up their backsides - so the nutrients are absorbed rectally, According to Urban Legend this gives a girl a big butt, but according to medical doctors it can lead to a nightmare of complications. Intestinal infections, fertility issues, etc.
I stumbled over that fact watch "State of Undress". You can watch the show at
