The square root of 69 is 8 something, right?
Cause I've been tryna work it out

from Rihanna (Ft. Drake) – What's My Name? Lyrics on Rap Genius

Meaning

Rap Genius Presents: Math with Drake

69 is mutual fellatio, and “8 (ate) something” is referring to cunnilingus. It’s also a continuation of his “word of mouth” wordplay from the previous lines. Really clever line on Drake’s part.

As an added bonus, the square root of 69 is 8.30662386… so Drake is mathematically correct
