Sick Pong
When one sick individual in a couple just can't keep his/her mouth off their gf/bf/fuckbuddy, passing on the virus that they will eventually get back from said gf/bf/other, creating a vicious tennis-like volley of sickness. The world must know.
"TAG, YOU'RE SICK!!!"
"eww guys, stop playing sick pong."
