Get the klong mug.
The name given to a loss of clear speech due to use/abuse of ketamine. Combines an existing loss of ability to put together a sentence with the slurring of words. Sufferers will find it very hard to "spit out" words.

Magically rhymes with "bong" and can be used to turn marijuana references into ketamine references.

Word is likely derived from the combination of 'k' and 'langue', the french word for tongue.
I had mad klong when I was talking to her last night.

Hits from the klong!
