The combination of being grumpy and drunk - as epitomised by Colin Bacon during late night phone calls.
"Hello Colin Bacon, How are you?"
"All women are fucking evil, you're all evil and just fucking dreadful!..."
"Oh dear, are you Grunk again?"
"All women are fucking evil, you're all evil and just fucking dreadful!..."
"Oh dear, are you Grunk again?"

My gay friend Grant got grunk last night, and had a threesome with two big bosomed ladies of the night.

an irrational, idiotic manbaby. The name derives from the latin word Gruuknalia (meaning uncontrollable rage). A grunk is a person who is incapable of basic human speech and communicates only via grunts, shrugs and inchorent crying. Many teachers at a school will try to take care of a grunk and try to contain him. But from the Non-stop screaming and shaking to the constant barrage of fully used diapers, grunk(s) will usually be distributed and sent to the SCP foundation to be contained securely.
"Have you seen Greg recently? He's been out of control and acting erratically..."
"I don't know, i'm suspicious he might be a Grunk."

Acting gay when getting drunk. Example: "Did you see Greg the other night, he had a six pack of beer and he was acting like a Grunk!"
