特仑苏也吥一定纯
[tè lún sū yĕ pōu yī dìng chún]
This nickname plays on the name of a famous Chinese dairy brand, Telesu (特仑苏), which is marketed as premium and pure. The second part, '也吥一定纯' means 'may not necessarily be pure.' It conveys a satirical or cynical attitude about things being hyped as purely good may not always live up to expectations.
