Baby Jello is another word/slang for a baby bubble butt. They are found on petite women, thus the reference to “baby,” not average to full size women. A bubble butt is defined as a nice rounded behind/ass, similar to that of a globe. They are very firm, sexy, and perfectly rounded anatomical masterpieces.
