A throat and upper respiratory ailment that results from sucking a lot of dick. Symptoms include congestion, a hacking cough, crying, bitching, moaning, and occasionally death. Affects women and gay men. Can be treated by such maneuvers as a donkey punch, a white dragon, and the danza slap.
Jen was being a bigger bitch than usual so Joe assumed she was suffering from the cum lung and danza slapped her.
