You can do it. It's an easy one

i 8 sum apple pi

“I ate sigma pie and it was delicious!” Sounds like something that’d show up on my university’s YikYak, alluding to eating out a sorority chick from Sigma Pi lol

Idk if that’s a legitimate sorority, but I know that regardless of the sorority mentioned someone would reply something like “wait till you try a pi phi 😜” and/or someone would say you’re going to get an STD from that particular sorority

Damn, I over thought it. I got "Imaginary cube sum of apple pi" before seeing the answers here.

This phone is as smart as apple pie.

"imaginary ate some apple pie"

I was close!
