A man who likes the taste of his own cum and enjoys drinking it, preferably after butt-sex, but not mandatory.
This person tends to be a douchebag, and is also usually very narcissistic. He thinks his cum tastes better than everyone elses.
"I can't believe Russ is a manager now."
"I know. He's such a douchebag. Did I tell you that after we slept together, he took off the condom and drank its contents?"
"Wow. What a jackmonk."
