Synonymous with ‘sick’
i.e.:
- insane
- ridiculous
- cool as hell
Often used in
exclamatory situations; the exclaimer, with this pronunciation, would appear to have a heavy
lisp and would emphasize the latter half of the word: replacing the ‘ck’ with a ‘
ga’ sound.
The speaker might be trying to say ‘thick’, as well. It’s hard to tell in these situations, but that is why, after all, people with speech impediments are often looked down upon in today’s society.
