And I bet my last nickel that she eff with Sweet Petey

from Nickelus F (Ft. Drake) – Number 15 Lyrics on Rap Genius

Meaning

“Sweet Petey” is Nickelus' nickname, as well as his Twitter handle

Another interesting thing is that he uses his own name in a smart word play:

Nickelus F. has also been abbreviated in some of Drake’s songs as Nickel F. Pay attention to the caps in this line:

“and i bet my last NICKEL that she "F” with sweet petey"

Notice too that that’s why he said eff instead of fuck
