awesomely lost in translation

Lucy came back from India bearing gifts, including this shirt that her daughter picked out for me. I love it, even if I’m not exactly sure what it means.
 


“cutie” — yes, I am
“nature” — yes please
“liner” — ??

And is the message that I should try being single? Or are we going for sorority Greek system spelling where “tri” equals 3, as in 3 single flip-flops? Either way, this shirt goes perfectly with my “Happy Birt Hday” mug. I know you’re jealous.
