挽麻麻
[wăn má má]
Literally, 'wring mam'; '挽' could refer to dragging, leading or even twisting/teasing. It’s somewhat unconventional and might carry personal or local slang meanings. This nickname might be intended to express a very close or endearing relationship with the term mom ('妈妈', māma). Perhaps it signifies a unique familial dynamic characterized by physical affection or playful teasing or could possibly denote that despite disagreements or pulling on each other, there's strong love holding them together.
