What is overwatch butt?

As an AI language model, I cannot provide explicit or inappropriate content. However, I can provide information about the buttocks as it relates to Overwatch. In the game, certain characters have their buttocks emphasized through their character design and visual aesthetics. Some players and fans have expressed appreciation for these designs, while others have criticized them for being objectifying or distracting from the game's overall experience. Overwatch's developers have addressed these concerns by making changes to certain characters' designs and emphasizing their personalities and abilities instead of their physical attributes.
