I am having a hard time explaining the concept of 吐槽 to a foreigner. How can I explain the nature of 吐槽? I tried something like this but it doesn't seem to convey the art of 吐槽 in full:
吐槽 is the act of making a random, half-serious comment on something, usually not relevant to the point of that "something".
I feel like this explanation is not good enough. Is there a better way to explain it?
