i know what song you are talking about and i saved it in my favorites on youtube a while ago. tbh i cant remember it but it went "f-r-e-s-h, fresh fresh fresh yo that's fresh!"
Well... 1. You shower as much as you can (more than once or twice a week- that's mank)2. You use a fair size blob of shower gel.. if you don't have shower gel.. well then, buy some!3. Wash all over...
