I, too, have sinned, and even sign emails to kids at college with "stay awesome, bro" which I hope they find vaguely ironic and hipsterish. But, honestly, OP, anything you say is going to be 1) dated in their eyes, and 2) appreciated by them. FWIW, however, I also say "you go, girl", "way to go, buckaroo" and "rock on with your bad self, dude/tte". All of these bring a smile.
