@ChrisChanBoi2 @redpillx2 @BigPompaPomp Yes and no. This isnt entirely true. Chimps, even monkeys, can be trained to do this with positive reinforcement. It also means different things depending on how wide their mouth is open, body language, etc It helps to know if theyre trained or wild to read certain expressions — PolitiTweet.org

@ChrisChanBoi2 @redpillx2 @BigPompaPomp Its when their mouth is wide open (space between teeth) and all teeth visible that it usually means theres a threat. They can be trained to smile like that as part of play though too. — PolitiTweet.org
