a retarded word meaning drunk and crazy initiated by possibly the worst "rapper" in the history of the world, besides Vanilla Ice, Lil John, who is only capable of sayin 3 words, which makes it all the more amazing that he came up with such a stupid word.
getting crunk has several meanings:
1.) to get banged up or damaged,
before throwing a punch: "get crunk bitch!
2.) to get drunk and/or stoned
"i'm getting crunk tonight"
3.) to have sex
"me and this bitch were gettin' crunk"
4.) to get excited
" i'm getting all crunk for this fight"
