No one knows all of your dirt like your best friend and in this section of funny birthday wishes for best friends that is pretty obvious. We have added several hilarious ecards that say things like, "Let's absurdly over-celebrate your birthday as much as people do Jesus's." and "Friends say "Happy Birthday!" Best friends say "Happy Birthday you nasty skank!" and these are just a couple of examples of the kind of wish you might send one of your best friends. You will find these here and so much more.
