For example:
* "Avianikkum" - "They're selling it (literally or figuratively)"
* "Entha kaaryam viikkunnu?" - "What are you trying to sell me?"
* "Nee athu viikkunnu?" - "Are you trying to convince me of that?"
It's important to note that the exact meaning of "vikk" can depend on the context and the speaker's intention.
