BOH

What the picture shows

The word "BOH!" is rendered in thick, rounded orange letters with dark outlines and glossy highlights, the O styled as a wide ring with a dark center, giving a cartoonish, bouncy look. Chatters likely use it as a playful, sudden exclamation to react to a surprise, jumpscare, or punchline in a stream.
