怪姥姥
[guài lăo lăo]
The term '姥姥' generally refers to maternal grandmother in Chinese. Adding a 'strange/weird/odd'(‘怪’) before it creates this particular username. However, without any specific cultural background information given, foreigners should be informed that it’s probably meant in an affectionate or whimsical manner, hinting that either the grandmother herself is a bit eccentric, or she plays a peculiar part within family stories or memories of the user.
