你的温柔秀给你爷看
[nĭ de wēn róu xiù jĭ nĭ yé kàn]
'Show your gentleness to me;' the second part 'you grandpa look' is an exaggerated phrase used humorously. This nickname could imply asking the owner, possibly a close relative like a grandparent, to show their gentle side as opposed to any stereotypical expectation of toughness or sternness.
