Green Day's Billie Joe Armstrong Calls Psy 'Herpes' & Psy LOVES IT! See His Reaction HERE!

Sounds like one cranky rock star woke up on the wrong side of the bed today!
Or maybe we just assume that because Billie Joe Armstrong’s hair screams bed-head, LOLz!!
For reasons we cannot fathom, the Green Day punk rocker is throwing down the gauntlet and everyone’s favorite international superstar — Psy!!!
On Billie’s official Instagram account, the rehab veteran posted a pic of Psy’s famous horsie dance with this caption:

“This dude is the herpes of music. Once you think it’s gone, it comes back. #herpes #flareup”

Whoa!!! HERPES!!?! That’s no bueno!!
The Gangnam Style singer, amazing samaritan that he is, shrugged the shade right the eff off!!
See his HIGHlariously understated reaction…AFTER THE JUMP!!!

Aww!! He’s thinks herpes are really cool! He’s AH-Mazingly sweet!
Hopefully BJA apologizes so these epic musicians can collaborate on a sweet new single!!
On a more serious note, always wrap it up kiddies!
Cuz Billy J is right — Herpes does NOT go away!
