不算强光但至少能亮瞎她
[bù suàn qiáng guāng dàn zhì shăo néng liàng xiā tā]
'Not so bright but at least it can blind her' is a funny way of saying that the person doesn't have outstanding appearances or characteristics but could catch others' eyes somehow, showing a self deprecatory but humorous attitude about oneself or someone the user cares about.
