相公猛如狼好久没下床
[xiāng gōng mĕng rú láng hăo jiŭ méi xià chuáng]
In a playful, intimate way, this name refers to an enthusiastic 'husband' being too strong in bed. The implication is that their partner has not gotten out of bed for quite some time due to how intense things get. It's a very colloquial expression that might have humorous connotations but would likely only be appreciated within Chinese contexts where such language and concepts are more familiar.
