Your feelins like Zulu, then nothing is a Shaka
Reference to Zulu warrior Shaka Zulu who united neighboring tribes to make a huge army.
“Your feelings like Zulu” refers to the Zulu Kingdom before Shaka, which was divided (she feels conflicted), and “then nothing is a Shaka” means that there is nothing to ease her feeling conflicted.
Shaka is also worldplay. Ye is saying that nothing shocks this person (nothin' is a shocker).
