COMPOUND:
思い出す (to remember) + 笑い (laughter)
NUANCE:
This often has a slightly embarrassing or socially awkward connotation, as laughing suddenly in public without an apparent reason can seem strange to others.
COMMON PATTERNS:
- 思い出し笑いする - to laugh at a memory
- 思い出し笑いしてしまう - to accidentally laugh at a memory
- 一人で思い出し笑い - laughing alone at a memory
NOTE:
思い出し笑い in public places like trains can be socially awkward, which is why it's often mentioned with ~してしまう (to do accidentally).
