Chunky monkey is a weird phrase that has been used for many years that really makes no sense! I suppose it means that you are fat but cute and playful and funny like a monkey? I don’t know I just feel like I would be offended if someone called me that… Anyway, throwing away those traumatic middle school memories and refocusing on this chunky monkey Romper Bodysuit. Your little monkey is of course chunky because it's a little baby but with this chunky monkey Romper Bodysuit you can call your baby something cute and not mean!
