I think it has to do with the tattoo because its the irony of the situation, "tera naa ahooga" meaning they will see the name of you, and he will have to tell him about her... if she had it and gave it to him...he could lie about it and say he got it from someone else or a needle or something, but the fact that her name is tatooed on her...he can't lie about it....yea maybe I am analyzing it to much lol
Kende Ne Seyane is a good song to and relates to Punjabi Culture...Respect your elder FOOLz!!
