You're pointless as Rapunzel with fucking cornrows

from Eminem – Rap God Lyrics on Rap Genius

Meaning

Rapunzel is a fairy tale where a princess lets down her long ass hair so a prince can climb up her hair and marry her and save her.

So if she had cornrows she wouldn’t have long enough hair to do anything.

Not coincidentally, perhaps Em’s most prominent and long-running beef was with someone who famously wore cornrows
