爆笑

1. Origins, structure, and basic meaning

• Structure: 爆笑 is read as ばくしょう and functions as a noun or with する for a loud burst of laughter.
• Basic usage: Use 全員が爆笑する for the people laughing and 会場が爆笑に包まれる for a hall filled with the audience’s laughter.

2. Common pitfalls and similar expressions

• Intensity and number of laughers
  • It denotes much stronger laughter than a slight smile. Both examples show a group reaction, but the word itself does not inherently require multiple people.
• People and venue as subject
  • 全員が identifies the actual laughers, while 会場は presents the collective reaction filling the space.
