很酷不走心
[hĕn kù bù zŏu xīn]
The net name suggests someone who appears to be very 'cool' but does not actually put heart or sincerity into actions or interpersonal relationships, reflecting a certain nonchalance and detachment. In China's social culture, being 'cool' is popular in young people, which means to have a calm mannerism that seems detached, uninterested.
