拉钩为何要上吊
[lā gōu wéi hé yào shàng diào]
Literally 'Why hang oneself after making a pinky promise?', the user contrasts something solemn like committing suicide with something casual and symbolic such as making a simple commitment with fingers crossed between two friends, pointing out absurdity and emphasizing confusion over why one would escalate emotions over what is usually just playful interaction.
